Change of Position Management Procedure in ECC 6 EHP 0

Hello Gurus,

Customer is on ECC 6, EHP 0

Requirement is to alter the way Forex Forwards/Options are being valued. Therefore, a new PMP would be configured and needs to be assigned in existing contracts.

Since, existing contracts are in use for more than an year; there are valuations posted on them. Of course, the customer does not want to reverse those valuations and we are left with only option of performing Valuation Class Transfer (TPM15M) in order to change to the new PMP.

Unfortunately, I notice in ECC 6.0, Valuation Class Transfer is available only for Securities with old TCode TPM15. The functionality is not available for Forex deals. I learn that TPM15M has been delivered only from EHP 5

Any suggestions on how to go ahead to change the PMP in this case?

Thanks,
