Please note we have different kind of Sale Orders Like ZIOR for standard, ZIRE for Exports, ZIEZ for SEZ and ZIDE for Deemed exports. Earlier , the tax conditions used to change based on the Order type. Like even if the Customer master with 2% CST ( Domestic sales) was used with ZIRE,ZIEZ or ZIDE then tax would become nil. But from recent time , this is not happening. Please find below example.
Customer code xxxx is normally used for domestic sales with 2% CST tax conditions. Some times they also export the material hence we use same code but different order type. But now the tax conditions are not getting changed and we have to manually change everytime such order comes. how to control this problem?
