Purchase Report

Hi

We want to design a new Receipts / GRN report. Which we need to submit for the Govt on the TAX & Excise returns. There is a lot of return and cancel of the Receipts done bcoz of the rate changes and the Qty while doing the reciept and while doing the tax calculations there is a lot of reverse and cancellation goes on . So we are unable to trace which lines are the perfect Receipt lines from which we can generate the Report from F4312.

Please kindly suggest , our process is correct process , please suggest us the correct condition for generating the report.
