Usersecurity debit and credit amounts on a maintenance worksheet

Hello,

This will be my first question on MOS and I'm curious to see what your thoughts are on this question.

Our receivable department has two userroles. One for the administration of debitamounts (A) and one for creditamounts (B).

For example, when we have a debitamount which we want to write off, user A should be able to do this (on a maintenance worksheet by selecting the WO entry type).

On the other hand we also want to write off a credit amount and now user B should do this (on a maintenance worksheet by selecting the WOC entry type).
