Hi,

Since you are using the Data element of that field, and generating the fun module for that field exit, so when you are navigating through your transaction, when you reaches that field and enters something , this automatically triggers that field exit.

reward if useful

please find the example below.

version might be different just look into the changes related to version.

If you followed the following process to create a field exit,

just create or change the related transaction.

Example Business Scenario for a Field Exit

ABC company would like to have the payment method field on the customer master filled in automatically for each customer master record. All customers should have a payment method of ‘C’ for payment processing of credits and rebates.

To accomplish this requirement, ABC company can set up a field exit on data element DZWELS. The necessary steps are detailed below . This example was configured in a 4.5B system.

1. IMG Menu Path: Tools ABAP Workbench Utilities Enhancements Project Definition Text Enhancements Field Exits Field Exit Create.

2. Enter the Data Element you are creating the field exit for. If you do not know the name, go to the screen with the field to be filled in. Hit the ‘Help’ button on the field and then ‘Technical Information’. The DATA ELEMENT is what you are looking for!

3. Hit ‘Continue’. This will take you to transaction SE37 to create the function module for the field exit.

4. The name of the function module will default in for you – FIELD_EXIT_DZWELS.

5. Hit the ‘Create’ Button.

6. Enter the Zxxx function group the field exit should be contained in. If you need assistance creating the function group, see the next section ‘Configuring a Function Group’ in this document.

7. Hit the ‘Continue’ button.

8. Enter the application for the field exit. In our case it is ‘F’ for Financials.

9. Enter the description for the function module.

10. The Import and Export tabs will each have one field. The import tab should have field INPUT for the current value of the DZWELS field. The export tab should have field OUTPUT for the new value of the DZWELS field. These two tabs will have these two fields automatically and won’t need to be changed for our field exit.

11. The Changing, Tables and Exceptions tabs will be empty.

12. The Documentation tab will have the INPUT and OUTPUT fields. You may add descriptions for these fields if you wish. It is not mandatory.

13. Save the Interface for the Function Module.

14. Hit the ‘Source Code’ button.

15. Enter the ABAP code for the function module. The code should check if the INPUT field contains a ‘C’. If not, the INPUT field and a ‘C’ should be concatenated into the OUTPUT field. Remember the payment method field can contain more than one value. You don’t want to delete a valid payment method by just inputting the ‘C’. This is why you need to concatenate the two values.

16. Check the syntax of your ABAP code by hitting the ‘Check’ button.

17. Save the function module.

18. Activate the function module.

19. Hit the green arrow back 3 times.

20. You will receive the pop up box to enter another data element. Hit the ‘Cancel’ button to return to the Field Exit screen. Your data element should now be in the Field Exit list.

21. Select the new data element in the Field Exit list by turning on the radio button to the left of the field. Notice the field program name is ‘Global’. This means the data element field exit would be for all programs and screens where the data element is used.

22. Hit the ‘Assign Prog / Screen’ button.

23. The Field Exit field can be blank or alphanumeric. For this example we are leaving it blank. It is used to create multiple field exits for the same data element and assign them to various programs / screens. The value placed in this field will force you to create a function module with this value at the end. For example, if we entered a ‘Z’ in this field we would be prompted to create a new function module with the name: FIELD_EXIT_DZWELS_Z. Because we are leaving it blank, it will use the function module we created above without the ‘_Z’.

24. Enter the program and screen where the field exit should be called. In this example it will be called for a customer create / change transaction in FI. To find the program / screen for a field, go to the screen and follow menu path: System Status.

25. Hit the ‘Save’ button. You will be prompted for a CTS request at this point.

26. Activate the field exit by selecting the fields’ radio button on the left. Then follow menu path: Field Exit Activate. This will prompt you for a CTS request as well.

27. You are ready to test the Field Exit.

28. To test this exit, create or change a customer using the FI create or change transaction: FD01 or FD02.
