GRN BATCH NUMBER

[petero@laballieds]

Hi forum,
1. have seen in table grns grnbatch wondering how it works any knowledge base looks can sort me out, my scenario is every grn is given a batch number/lot number which can be used for traceability, can this be the case .
2. I want to have a direct goods receive without passing through LPO shall i modify the GoodsReceived.php script or there is some script out there.
