Hello Adam,
thanks a lot for your answer!
We tried out almost everything, including your proposal.
The system is validating our IF-clause and it's working - we saw it from the messages shown.
What I have written to Cornelia before, was, that the system creates different iterations for the IF-clause and the FOREACH-loop, that's why it's not working in that way.
ZPROVERT is a quantity with a fixed quantity unit "%".
0AMOUNT is a value field, linked to the 0CURRENCY key.
I'll try to have the currency key in the changeable operands.
Maybe your hint is solving the issue somehow.
Regards,
Christoph
