In R/3 we have a config setting, which can enable SAP to determine Tax rate based on Document Date. This function is more logical as the document date is the date on which services are rendered and accordingly rates to be applied.
I am looking for similar feature in FI-CA but miss it. Currently, all document posted ( Bills & Adjustment ) consideres Posting date as service rendered date and current taxes are being computed.
Can someone help in letting me know if i am missing any configuration or If RMCa is designed to work this way only and what could be the reason for this logic.
