rejection of material

Hi,

there is requirement where PO, GRN, & Invoice has been done at legacy data for particular material. Now in SAP client uploaded thae stock data. Now transfer posting of material done in SAP. Then it went ot quality. But in quality, material has been rejected completely. Now the stock is in block stock.

Kindly suggest me the financial impact like whether it will hit the liability a/c while issuing credit note & how the intial upload stock a/c & vendor a/c will be adjusted.

Regards.
