SAP Message RQ044 - Only in special cases should the posting date differ from current date

Diagnosis
In the posting date selection, you should normally specify only thecurrent date so that, during payment advice comparison, the systemselects only the items that were posted today via bank statement entry.Otherwise, the system will select items from the past which probablyhave already been compared against payment advices and thus should notbe used for a new comparison.
Selecting several days may be advisable, for example, if payment advicecomparison was not carried out yesterday.
