Reading Dynpro values after PAI and Buttons with Functioncode 'E'??

[oliver_schmidt1979]

Hi there,

this is my first question for the Community, so I hope this discussion pool is right and no one else asked this question before:

So here is my problem:

I have called a Dynpro and defined in PAI:

PROCESS AFTER INPUT.

  MODULE DYNPRO_CANCEL AT EXIT-COMMAND.

and some field checks :

FIELD WA_VERARBEITUNG-KUNNR MODULE KUNNR_PRUEFEN.

In Module DYNPRO_CANCEL I process the CANCEL, BACK and EXIT Buttons with Functioncode 'E'  !

Functioncode 'E' to override the Field checks.

Now I want to create a Message for this Cancel-Buttons like 'Data have change. Would you like to save?'.

For that I have to check the Dynpro values for changing.

So here is the Problem because at Functioncode 'E' the Dynpro gives only ok_code back and no values to check them against the original wa (workarea).

I have tried to work with CALL FUNCTION 'DYNP_VALUES_READ' to read all the data manually, but the return values are all Char255 and I can't convert all values back in original data. I can convert most of them but not for all 😞

So here is the question:

Are there any other option to realize such a scenario like reading Dynpro values after PAI and Buttons with Functioncode 'E' or comparing the Dynpro values with workarea at this time???

I hope I can explain this question correctly and you have an answer for this problem.

Thanks a lot for helping.

there is a system variable available and populated to 'X' when any screen field value(s) is changed/manipulated.

Hello Oliver,

Try to do this using at-datar or let me know if it doesn't work.SY-DATAR is to be used along with a flag.

In PAI set flag using SY-DATAR.

ie

if sy-datar is not initial.

flag = 1.

endif.

Now in

Module exit_command..

if sy-datar is initial and flag is initial.

...

else.

.....

endif

endmodule

Wow, thanks a lot Hiran Kumar Pabba and D. Chia.

Sometimes you work in one direction and you forget the simple things.

That's it and it helps me a lot.

Thank you very much.
