Release Strategy for PO

Hello,

I need to create PO Release Strategy based on Total/Gross/Effective value (EKPO-EFFWR) of PO. I am aware of the solution using user-exit EXIT_SAPLEBND_002 with the field CEKKO-USRN1 configured to receive the EKPO-EFFWR value.

But this solution doesn't take into account currency conversions. I could have a PO in USD or GBP or INR whereas the Release Strategy is based on INR only.

Pls advice if anyone has a way to include currency conversions in this.

Thanks.
