How to update a value into a parameter based on the value from another parameter

[former_member228002]

Hi, I have the following code that is NOT working. I need to display the value from a table based on the selection from the first parameter statement. Then I need to update a table form the input in the third parameter field. Any ideas on how to resolve this? The second parameter p_lglnum is NOT getting updated when selecting from the first parameter, p_numgr1.

Your code is executed in PBO? (AT SELECTION-SCREEN IUTPUT)

The code is a stand alone report. When I select the value in the first parameter, it should populate the second parameter immediately.

Work with SELECTION-SCREEN BEGIN|END OF SCREEN and CALL SELECTION-SCREEN. Execute the latter in a DO-loop and leave the loop if F8 is selected. The ABAP Keyword documentation contains lots of examples for selection screen handling.

Thanks, do you have a sample code?

If you can display your first parameter as a list box then you can trigger a PBO when the user changes the selection. During the PBO you can then easily change other parameter values.
