Exchange Rate Fixed Indicator in PO coming by default
I have problem wherein at the time of PO creation I select account assignment catergory as Network and enter Material, plant and other information and after that I enter Network.
As soon as I enter network the exchange rate in the header gets changed and also the Exchange Rate Fixed checkbox gets automatically checked. It seems that it is a pre-configured settings for exchange Rate and exchange rate checkbox.
Please advise where to check so that I can track down from where the exchange rate is coming in.
