Unable to find FM or BAPI for Partial SD Reversal

Hi,

We have requirement in business wherein we would like to perform partial SD reversal.

So as to achieve this, there is option in FPSEC2 with push button "Clear Outstanding receivable".

I have even tried SE30 and SE80 but in vain.

I could only find BAPI_CTRACSECURITY_REVERSE and FKK_S_SEC_REVERSE but those are for full reversal.

If tried partial reversal for SD where partial payment was received then following error triggered, "Security deposit 11000422 cannot be reversed (status = 03) ".

So would appreciate if any suggestion which can assist in resolving issue at hand.

Regards,

Paresh
