CRRM field changed in F0413

Hi All

After inquiring an old K batch (from 2010), the batch status changed from Posted to Pending on the Header Status of P0011 in PD (Production Environment).

After comparing the F0413 from PD and PY (which was not touched), the CRRM field has being updated from blank to D in one of the records (PD) . See bellow payment 366923, which explains the change of status.

How could this happen?

Thanks in advance.
