FPCPL Background Execution through FM

Hi,

I need to clarify the payments in the batch run without any manual interference.

I have tested FM FKK_PAYMENT_BATCH_CLARIFY_ITEM for clarifying the items. After executing this FM stand alone and passing the import parameters for clarifying, it passes control to T code FPCPL screen for clarification. There we need to click on POST button then only that item will get clarified. But in case of batch run we can not follow this approach. So kindly guide on this which FM should I use?

Regards,

Vineet.
