Interpretation Algorithm in Electronic Bank statement.

Dear Experts,

I am facing a very serious issue with electronic bank statement interpretation algorithm.

There are two internal transaction

KBCH - Bank charges

KBOC - outoing manual payments

External transaction - FTFR

In OT51 this configuration exists

FTFR - KBOC 000: No interpretation Dummy entry - not assignable

But for both the transaction bank has only one external transaction FTFR. Now the user facing issue while posting the transaction, he has to manualy change the KBOC to KBCH everytime for bank charges and want to default KBCH instead. The ext transaction FTFR appears in the electronic bank statement not only for bank charges but for other transactions as wel.

We have looked at a bank statement together and have established that part of the record for bank charges is always unique, is it possible to interpret this somehow using the "Interpretation Algorithm" in OT51?

A bank charges record in the file looks like :

61:1011181118DX3892,67FTFRNONREF// Note : this line for manual outgoing payments

:86:999/00TFRFTRFC MAR ASIA PTE LPET005450322

:61:1011151115DX6,00FTFRNONREF// Note :FTFR the external transaction

:86:999/00TFRFCHGBIB-3190533160*PET018744319 Note: TFRFCHGBIB the identifier for bank charges, the :86:999/00 always seems to be the same as well

So, can you help how to proceed either interpretation algorithm or any user exit ? Please reply asap.

Thanks in advance
