Hi,
Check the tables FKK_INSTPLN_HEAD & FKK_INSTPLN_HIST.
These tables contains the header Data for Installment Plan and the Installment Plan History.
Also check the table DFKKCOH and DFKKCOHI for Correspondence type 0005.
In here, you will get the data against the IP which needs to be sent.
Hope it helps...
Thanks,
Amlan
