I have gone through the net and found that the MRP indicator is there to support this case in SAP but the threads are confusing
suppose i have a PO for 120 rs which includes the excise (not considering other tax for the sake of simplicity)
after GRN we will come to know about the excise part
and in GRN we have only Part1 capturing option not part 2
for part2 we use J1IEX
As in your case, you have following components in dealer invoice:
Material Price = 100/-
Excise Duty = 13/- (BEDECessSECess)
Margin of Dealer = 5/-
VAT @2% = 2.36
Grand Total =120.36
So create PO for to Dealer Vendor with Base Price as 118/- by selecting tax code(V1) which is having VAT as 2% ( Total PO value will be 120.36 )
Now go for MIGO directly(as per your excise setting) or MIGO & then in J1IEX, select MRP indicator in miscellaneous tab, Enter Assessable value 105 as in Excise tab Item level and enter the excise values 10 in BED, 2 in ECess , 1 in SECess manually, check all values are correct & save the document.
Do MIRO, use proper tax code(C8) which must be different then PO (a tax code matching of value ieu2026..10 % BED, 2 % ECess , 1 % SECess and 2% VAT) edit base value as 105/- in item level , select calculate tax check box, enter the amount in header as proposed by the system (120.36), simulate & post the document invoice document.
