as per our client requirement while posting MIGO, the document date has to be considered for exchange rate , SO I have written a simple substituion in OBBH, with pre requisites as company code = AB01 and transaction code = MIGO_GR, BKPF-WWERT = BKPF-BLDAT.
I have done all the required de selections in table GB01.
But system is not able to substitute translation date with document date.
I have gone through some links SDN, but I couldn't find the proper solution.
we have two sap notes for substituting the document date in MIGO and MIRO, but we can implement with country level. But we have many company codes in same country, substitution is applicable for only one company code.
the manual option of ticking fixed exchange rate field in purcahse order is not accepted by the client, as it involves manual intervention. more over system will post exchnage rate differences also in this case, client donot want that.
So, how can we develop substitution for translation date?
