Event to update custom fields after FPMA transaction

Hello,

I have a requirement in FI-CA where I have to update custom field of table DFKKOP after the mass clearing (FPMA transaction).

I identified the events 10 (FM -> FKK_SAMPLE_0101)1 and 20 (FM -> FKK_SAMPLE_0020) in transaction FQEVENTS. But those are not useful for my requirement.

Please let me know which event can be used to update the to update the custom field of table DFKKOP after the Mass clearing.

Thanks in advance
