User Exits in FI/CO

原创 IT综合 作者:zhujianfu 时间:2004-11-18 14:30:14 0 删除 编辑
R/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.[@more@]

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.


· 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 be thoroughly tested when upgrading to ensure the system will still work as implemented.

Configuring SAP Enhancements

Basic 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 Enhancements

Company 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 Steps

1. Tools ABAP Workbench Utilities Enhancements Definition Utilities List Enhancements

2. Do not execute this without any parameters! There are too many Enhancements and 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 for an 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 Here

4. Look through the list until you find the Enhancement for User exits: Customer Master Data.

5. Double-click on the enhancement SAPMF02D. This will take you to the details of the Enhancement and list the function modules included in the Enhancement.

6. To continue, double-click on the function module EXIT_SAPMF02D_001

7. This will take you to the source code for the function module. Click on the Import tab to review the tables/fields that are available for the Enhancement (see Figure 2).

Figure 2. The Tables That Are Available for the Enhancement

8. To view the tables/fields that can be changed in the function module, click on the Export and Changing tabs. For this function module, these tabs are empty because you can only validate data. You cannot change any fields in this enhancement.

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 Figure 3).

Figure 3. Your Program Will Begin After the Include Statement

11. Double-click on the Include. You will be prompted to create the include. Click on Yes to create.

12. At this point you will be prompted to enter a development class and to create a transport 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' and

i_kna1-brsch = ' '.

message e001(F2).


Figure 4. The ABAP Code You Need to Enter

14. 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 message number 001. Normally, you will create your own message within your own message class. All customer message classes must begin with a "Z" and are created in transaction SE91.

16. Save the program.

17. The next step is to create the project. Go to transaction code CMOD or follow menu 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 Name

20. 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 a transport 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 Here

25. 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 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 Variables

Example Business Scenario for User Exits

Company 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 with the technical team for the correct development class.

3. At the initial ABAP Editor screen, enter your new "Z" program name, select the Source 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):


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_field

where hkont = accit_glx-hkont and

geber = accit_glx-geber and

fkber = accit_glx-fkber.


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 Ledger Basic Settings User Exits Maintain Client Specific User Exits.

8. The entry to maintain is application area GIMV: Variable Field Movement. Enter your "Z" program (see Figure 15).

Figure 15. Enter Your "Z" Program in the Application Area GIMV: Variable Field Movement

9. Save the changes.

10. The final configuration step is to assign the User Exit in the variable field movement for your special ledger table. In the IMG: Financial Accounting à Special Purpose Ledger à Basic Settings à Master Data à 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 through User 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. The Exit 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!
