traceability for WM

Dear experts

After MIGO, system generate a GR number(goods reciept number) which is same to material document number. The GR number can be display in quant with LS23. But material staging from warehouse to PSA, the quant and GR number in WH storage bin will be change to PSA's quant. The GR number is also changed. If production line return the material from PSA to WH, the GR number from system is not original one. So it will have some problem if we want to return it to vendor. Because with GR number, we will know the relevant PO number.

Please advise how to solve the problem.

    This is behaviour of standard system.

    When adding materials to existing stock, quant characteristics are combined. This means that the quant information in the stock that is added to existing stock is lost and takes on the quant characteristics of the stock that is already stored in the bin. This includes, for example, the goods receipt date. Be cautious where FIFO stock is concerned. This quant information does not go away until the storage bin has been completely emptied.

    You have to use batch management to achieve your goal, there's no workaround in my opinion.

      Dear Csaba

      We use batch managment for some materials. But it is very difficult to follow the rule.

      Is there any other way? Currently after materials go to the PSA, the original infomation will be lost.
