how partial inspection is done for a inspection lot & vendor payment done based on inspection result

Dear Gurus,

In our business 1000 bag material is received in one material document. So one Inspection lot is created.

Now business take randomly 10 bags from that 1000 bag & inspected. The Bags are inspected on various parameters such as Weight , Fabric , Valve Size , Cross Sec Area, Print Quality , Stitching Thread , etc . The values for all this types of parameters are prepared in an excel sheet in a prescribed format.

The Values for each Quality Parameters are then matched with the desired prescribed average figures.

Based on the Values which deviate from "Average" figures , deductions are computed

Logic is 1% for single defect in a bag for 1 parameter . Likewise if more defects is found then add 1% in multiples

1. e.g 1% + 5 defects then .05 * basic Raw material cost .

This figure along with proper description is recorded under "Remarks" column of the report format and send to Accounts department for the

  deduction process from Vendor

we need to capture the inspection parameters in system as per the above process.

And please tell me how I configure this process in SAP .

Thanks & Regards,
