Postings made to a Dummy profit center

Hi,

When checking the 1KEK list (Transfer Payables & Receivables to PCS), we noticed that many postings were made on the Dummy profit center.

This happened when the Special G/L indicator was used (E.g. for doubtful customers, for transfer to a Factoring company).

Where can I make the settings for picking up the profit center automatically?

Thank you.

Kind regards,

Linda
