We want to post a document with multiple line items (all of them having different exchange rate) using FIDCCP02 idoc. When we pass amount in both document and local currency, SAP still recalculates exchange rate based on current date or translation date at header level. In case it is not possible to post different exchange rate, we want to hardcode a calculated exchange rate at header (SAP still seem to not take our manual exchange rate and determines the exchange rate again).
Is there a way to post different exchange rate at item level or send a different exchange rate just a header level (ideally prefer different exchange at item level)
