增强开发指南：如何增强操作ADDWT往CRT表中插⼊⾃定义类型的⼯资项条⽬？操作ADDWT是SAP HCM⼯资计算配置中最常⽤的⼀个操作，可以往IT、RT、LRT等内表中插⼊记录，也可以往⼯资项累计表CRT表中插⼊记录。

使⽤语法 ADDWTCnnnn可以往CRT插⼊记录，但默认的累计类型是Y，标准系统不⽀持其他的累计类型，如M、Q、U。

操作ADDWT针对参数C做处理的标准代码为：WHEN 'C'.* XFG note 410458: deactivate ADDWTC for Canada and USAIF calcmolga = '07' OR "Canadacalcmolga = '10'. "USAMESSAGE e031(hrpay99calc) with i52c5-ccycl into dummy.MOVE-CORRESPONDING sy TO error_msg.PERFORM errors_t100 USING error_msg.ELSE.IF ot-anzhl NE 0 OR ot-betrg NE 0.MOVE-CORRESPONDING ot TO crt.crt-cumty = 'Y'. "Year-To-Date QXOK146693COLLECT crt.ENDIF.ENDIF.可以看到使⽤操作数C的时候只能往CRT中插⼊累计类型为Y的记录。

在项⽬实践中，有时候需要使⽤⾃定义的累计类型，如9-年度累计（上年12⽉到本年11⽉），如果想使⽤ADDWT往CRT 表中插⼊累计类型为9的⼯资项记录，标准参数不⽀持，这时候可以对ADDWT做增强达成⽬的。

增强⽅法：1）使⽤TCODE PE04 修改操作ADDWT参数值X 的属性，使其可以为国家分组中国（28）所⽤，注意这⼀步是系统修改，需要输⼊Access Key；2）点击屏幕上⽅的源代码按钮，主程序⼀律选择HCNCALC0，在INCLUDE程序RPCBU409_OPADDWT可以看到ADDWT 的源代码：FORM FORM opaddwt. "formerly ADDFLsaveot = ot.PERFORM vcollect.ot = saveot.ENDFORM.3）双击FORM vcollect，在INCLUDE程序RPCBU209可以看到FORM vcollect.的源代码，定位到代码段。

User Exits in FI/COby Tami Becker, SAP Platinum Consultant, SAP America, Inc.OverviewR/3 provides three "customization spots" that allow you to enhance FI/CO features without modifying the standard code. Although often collectively referred to as "user exits," two of the three have different names. SAP Enhancements are used to expand the standard functionality within SAP. Enhancements use function modules and are called from the standard SAP code. Each module in the system has a set of delivered enhancements that help companies expand the standard functionality where they need it. Enhancements were new in release 3.0.The Open FI Interfaces or Business Transaction Events are also used to expand the standard functionality within SAP. These events are defined in the IMG. Business Transaction Events were new in release 4.0. They are not available for all modules and are not called on all integrated transactions into FI as of release 4.5B. This will change with each release and should be retested.The older User Exits in FI/CO are "Z" programs that are defined in table T80D for client-dependent user exits, and in table T80I for client-independent user exits. These are also used to expand the standard functionality within the FI/CO modules. These User Exits have been available since the early releases of SAP. All of these FI/CO User Exits are listed in this document in the Configuring User Exits (Older). The list is included because these User Exits are not a part of the Enhancements or Business Transaction Events and do not have an Info System for searching.Benefits∙Standard SAP functionality can be enhanced without modification to the standard code.∙Upgrades do not erase the functionality and it does not have to be re-transported or re-entered into the system. The enhancements should bethoroughly tested when upgrading to ensure the system will still work asimplemented.Configuring SAP EnhancementsBasic Steps in Configuring an Enhancement∙Find the appropriate Enhancement.∙Enter the ABAP code in the "Z" program within the function module.∙Create a project.∙Add the Enhancement to the project.Activate the project.Example Business Scenario for EnhancementsCompany A has a requirement to validate all customer master records created with a U.S. address. The U.S. entity reports on the industry field on the customer master. This is only a U.S. requirement and should not be required for the other countries, so the field status would not work. To accomplish this requirement, Company A will need to set up an Enhancement for the customer master transaction. The necessary steps are detailed below with screenprints. This example was configured in a 4.6C system.Detailed Steps1.Tools ABAP Workbench Utilities Enhancements DefinitionUtilities List Enhancements2.Do not execute this without any parameters! There are too many Enhancementsand it will probably time out. You’re searching for a customer master exit.Enter *mast* in the short text (see Figure 1). You’ll start there. Searching foran exit can be tricky, so make sure you try several things before giving up.3.Execute the search.Figure 1. Start Your Search for a Master Exit Here4.Look through the list until you find the Enhancement for User exits: CustomerMaster Data.5.Double-click on the enhancement SAPMF02D. This will take you to the detailsof the Enhancement and list the function modules included in theEnhancement.6.To continue, double-click on the function module EXIT_SAPMF02D_0017.This will take you to the source code for the function module. Click on theImport tab to review the tables/fields that are available for the Enhancement(see Figure 2).Figure 2. The Tables That Are Available for the Enhancement8.To view the tables/fields that can be changed in the function module, click onthe Export and Changing tabs. For this function module, these tabs are empty because you can only validate data. You cannot change any fields in thisenhancement.9.Return to the Source Code tab.10.Scroll down until you see the Include statement in the program. The "Z"program listed after the Include is where your code will be written (see Figure3).Figure 3. Your Program Will Begin After the Include Statement11. Double-click on the Include. You will be prompted to create the include. Clickon Yes to create.12. At this point you will be prompted to enter a development class and to create atransport request. If you do not know which development class to use, please contact your technical team.13.Enter the following ABAP code into the program (Figure 4):** User exit to ensure that all US customers have a group key* entered on the customer master.*if i_kna1-land1 = 'US' andi_kna1-brsch = ' '.message e001(F2).endif.Figure 4. The ABAP Code You Need to Enter14. Note that the table name matches the table name in the import tab tables.15. In this example you are using the standard message class F2 with messagenumber 001. Normally, you will create your own message within your ownmessage class. All customer message classes must begin with a "Z" and arecreated in transaction SE91.16.Save the program.17.The next step is to create the project. Go to transaction code CMOD or followmenu path: Tools ABAP Workbench Utilities Enhancements Project Management.18.Enter the project name; begin the name with a "Z."19.Click on the Create button.Figure 5. Click on Create After You Type in the Project Name20. Enter in a description for the project.21. Click on the Enhancement Assignments button.22. You will be prompted to save the enhancement. Click on Yes.23. At this point you will be asked for a development class and to create atransport for the project. You may use the same one created when adding the ABAP code to the function module.24.Enter the name of the enhancement SAPMF02D (see Figure 6).Figure 6. Enter the Name of the Enhancement Here25.Save the project.26.Back out of the enhancement assignment.27.Activate the project by hitting the Activate button.The SAP Enhancement is ready to be tested! Try creating a customer with U.S. as the country and a blank group key. Be sure to test one with a group key to make sure the message is not displayed in error as well.Configuring Business Transaction EventsBasic Steps in Configuring an Event∙Make sure the application is active for Business Transaction Events.∙Copy the sample interface function module into a "Z" function module.∙Enter the ABAP code into the source code section of the new "Z" function module. You may choose to create a "Z" program to enter the code into andthen insert the "Z" program into your function module source code.∙Activate the function module.∙Assign the function module to the event, country and application.Example Business Scenario for Business Transaction EventsCompany A would like to copy the group key field from the vendor master into the allocation field on all the line items within a vendor invoice and payments, including the vendor lines. This requirement assumes only one vendor is posted to in a document.To accomplish this requirement, Company A will use the Business Transaction Event 1130, Post Document: SAP Internal Field Substitution.1.IMG Menu Path: Financial Accounting Financial Accounting GlobalSettings Use Business Transaction Events Environment Infosystem (Processes).2.Find the correct Business Event. You are updating a field, so you select theProcesses Info System instead of the Publish and Subscribe Info System.3.Execute the search with the defaults.4.Find the correct interface for updating a document: Post Document: SAP-Internal Field Substitution (see Figure 7).Figure 7. Find the Correct Interface for the Business Event5.Put your cursor on the event and click on the Sample Function Module button.6.You are now in transaction SE37 – Function Builder. This is the function module(sample_process_00001130) you will need to copy into a "Z" name functionmodule for your coding (see Figure 8).Figure 8. This Is the Function Module You Need to Copy Your "Z" Name Function Module7.Click on the Copy button.8.Enter the "Z" function module name in the To Function Module field (see Figure9).9.Enter a Function Group. If you need to create a "Z" function group, go totransaction code SE37 and follow menu path: Go to Function GroupsCreate Group. A function group is a logical grouping of function modules, and the ABAP code is generated for function groups. You will be prompted for adevelopment class and transport when creating the function group.Figure 9. Enter Your "Z" Function Module Name Here10.In Function Builder (transaction SE37), enter the new "Z" function module. Clickon the Change button.11.The system will default into the source code screen where you may enter yourABAP code.12.Notice the tables available for the code. Additional tables may be declared ifnecessary.13.Enter the following source code (see Figure 10):tables: lfa1.data: z_groupkey like lfa1-konzs.z_groupkey = ' '.loop at t_bseg.* check for vendor lines. If one is found, read the vendor master and* retrieve the group key field.if t_bseg-koart eq 'K'.select single konzs from lfa1 into z_groupkeywhere lifnr = t_bseg-lifnr.endif.* Move the group key field into all line items allocation field.loop at t_bsegsub.t_bsegsub-zuonr = z_groupkey.modify t_bsegsub index sy-tabix.endloop. "t_bsegsubendloop. "t_bsegFigure 10. The Screen Where You Enter Your Source Code14.Save the function module.15.Back out to the main Function Builder screen by clicking on the green arrowbutton.16.Activate the function module by clicking on the Activate button (see Figure 11).Figure 11. Activate the Function Module from This Screen17.Assign the function module to the event in the IMG: Financial AccountingFinancial Accounting Global Settings Business Transaction EventsSettings Process Function Modules of an SAP Appl.18.Hit enter past the warning messages that this is SAP data.19.Click on the New Entries button.20.Enter the process for your interface. In your example it is 00001130.21.Enter the country the interface is valid for. If it is valid for all countries, leave thisfield blank.22.Enter the application the interface should be called for. If it should be called for allapplications, leave this field blank. Please note that not all integrated transactions are programmed to go through these interfaces! You will need to test to find out!23.Enter the new "Z" function module (see Figure 12).Figure 12. Enter Your New "Z" Function Module Here24.Save the settings. At this point you will be prompted for a CTS number for theconfiguration change.25.The Business Transaction Event is complete! You are ready for testing. Configuring User Exits (Older)Basic Steps in Configuring an User Exit∙Create a "Z" program for the User Exits and enter the necessary ABAP code.∙Enter the new program name into table T80D.∙Configure the application to call the User Exit.List of User Exits∙Variable Field Movements∙Substitutions in FI, CO, PCA∙Validations in FI, CO, PCA∙Rollups in SPL∙Fixed Field Movements in SPL∙Cost Center Summarization on Detail Screen∙Sets Formula VariablesExample Business Scenario for User ExitsCompany A would like to add a "Z" field in the Special Purpose Ledger to capture a Business Unit field for reporting. They have used all the standard SAP fields such as Business Area and Profit Center. The field will only be used for reporting and is only needed in the Special Purpose Ledger. You created a special ledger table (ZZSPL1) with field Z_BUNIT and need to populate this field based on a combination of G/L account, fund and functional area.To accomplish this requirement, Company A will use the Variable Field Movement User Exit. To make maintenance easier, table ZZBUSUNIT was created with the G/L account, fund and functional area fields as key fields, and the business unit field as a non-key field. You generated the table maintenance so the table could be updated using transaction SM30. SAP users update the business unit determination rules in table ZZBUSUNIT by entering the G/L account, fund and functional area, and then the business unit that combination should be posting to. The User Exit will read table ZZBUSUNIT using the G/L account, fund and functional area from the posting transaction and determine the business unit. The steps for using the user exit are detailed below. This example was created on a 4.6C system.1.Copy the delivered template User Exit program RGIVU000_TEMPLATE into a"Z" program. Follow menu path Tools ABAP Workbench Development ABAP Editor (transaction code SE38). In early releases, the delivered program was RGIVU000.2.You will be prompted for a development class and a transport. Please check withthe technical team for the correct development class.3.At the initial ABAP Editor screen, enter your new "Z" program name, select theSource Code button and click on Change (see Figure 13).Figure 13. To Enter Your New Code, Select Source Code and Click on the Change Button 4.Enter the following code in the User Exit (Figure 14):FORM E01_MVC USING FROM_FIELD TO_FIELD.to_field = 'CORP'. "Set a default business unit.* read table zzbusunit to determine the business unit field.select single z_bunit from zzbusunit into to_fieldwhere hkont = accit_glx-hkont andgeber = accit_glx-geber andfkber = accit_glx-fkber.ENDFORM.Figure 14. Enter Your New Code at This Screen.5.Activate the program by clicking on the Activate button.6.Change the configuration in the User Exit table to point to your new "Z" program.7.Follow the IMG menu path: Financial Accounting Special Purpose LedgerBasic Settings User Exits Maintain Client Specific User Exits.8.The entry to maintain is application area GIMV: Variable Field Movement. Enteryour "Z" program (see Figure 15).Figure 15. Enter Your "Z" Program in the Application Area GIMV: Variable Field Movement9.Save the changes.10.The final configuration step is to assign the User Exit in the variable fieldmovement for your special ledger table. In the IMG: Financial Accounting →Special Purpose Ledger → Basic Settings → Master Data → Maintain Field Movements. Field movements control how the fields in a special ledger table are populated. They can be populated straight from other fields in a posting or throughUser Exits.Figure 16. After You Assign the Business Unit Field and the G/L Account, the Exit Field Should Contain U01.11.Assign the business unit field as a receiver and the G/L account as the sender. TheExit field should contain U01 (see Figure 16).12.The User Exit number U01 calls User Exit E01_MVC form in the "Z" program.13.Save the field movement.14.You are ready to test your User Exit!© Copyright SAG AG 2002。
