FITV PR05 - check on receipts data

Hi everybody,

We use transaction <b>PR05</b>.

We need <b>to do specific checks in order to print error messages</b> when we create or modify receipts for a trip (for example we want to check total amounts and create new receipts lines if amounts are too high ... ).

We use the user exit <b>'FORM USER_CHECK'</b> in include <b>'MP56TFEX'</b>, it works fine when we create a receipt <b>but not</b> when we try <b>to modify receipts data via the receipts additional data popup</b> (appears after double click on receipt line).

To control receipts data I also tried user exits FITR0001,FITR0002,FITR0003,FITR0005 and BADI's like FITV but it doesn't work.

Do you know other user exits or BADI to check receipts data in PR05 ?

I can't believe that there is no way to check receipts data !!!!!!!!!!!!!!!!!!!!!!

Thank you very much.
