Hi Taro,
We have setup a similar requirement in IHC with provisional and final posting. Final posting picks a different exchange rate type and the gain/loss is being sent to the subsidiary.
However the issue we are having is the the EBS in the subsidiary side. In EBS, in posting area 1, we cant post foreign currency if my understanding is correct. Hence we have defined a rule to include posting area 2 as well. In posting area 2, it is posting in foreign currency as well. However it is picking the M or average rate in posting area 2 and not the IHC specified rate which is there in the bank statement generated from IHC as well.
It would be great if you can throw light on how you managed on posting the bank statements in the subsidiary side.
Regards,
Ravi
