    you can use

    LSMW

    CATT

    ABAP

    master data can be uploaded using LSMW as master data does not have any associated financial impact .. But transactional data like POs, Stock, open rservations etc will have financial implications

    LSMW does not provide any new way, you can start direct and batch inputs (own recorded and SAP provided) to load the data, and you can use IDOC and BAPI technologie as well from within LSMW.

    As LSMW generates more or less the code based on the target data structure used to load the data, it saves you a lot time.

    And it gives you still the option do add code as much you want.

    for open purchase orders that will not be received until after you start up then you'll need to enter them in SAP via ME21N and then receive them with MIGO when the material actually shows up. Most projects I've worked on have tried to close out all open PO's in the legacy system before cutting over so you don't have to go through this. The same goes for open sales orders. You have to be careful here because if you mess it up you could end up creating duplicate PO's and duplicate sales orders. What I mean is your supplier might have a PO from the legacy system that he is shipping against and if you create it in SAP without closing out the legacy PO he may think you want more material. Or you can create your own program
