Third party order already created. I have deleted purchase requisition and Purchase order.

Could you please help to resolve the issue. How to delete the sale order?

Senthil

    Hi,

    You cannot change the unit of measure for the material once any transaction is done using that unit.

    It throws error as below.The base unit of measure cannot be changed; choose "Display errors"

    Instead you can use alternate unit of measure if you want to have a new unit for that material by going to basic data view and select additional data and unit of measure.

    Thanks

    sales orders have to be rejected.

    However, SAP will keep complaining that the documents exist, because they exist (they only got a deletion indicator).

    SAP allows a change of base unit only after you have archived all dependend documents.
