I have a specific requirement.
In a screen (dialog prog) for a particular filed(field1) the PBO will be called first and then after input that field would be disabled and corresponding PAI should be called.
Now for the next text box(field2) the PBO module attached to it would be called and then after input PAI for that screen element would be called. Now when field2 will be populated the state of field1 will remain unchanged.
Please note that the value for field2 will be selected based upon the value selected for field1.
There are altogether 5 text boxes in the screen. After populating all the 5 text boxes, the PAI will be called again based upon the 5 fields to call the ALV grid display.
Please give me some idea, how to proceed with the coding.
Thanks in advance.
