Delete old material reservation - Can't find source
I have a reservation that was created automatically, so I cannot delete/modify it through MB22. I have read that the referencing document needs to be deleted first (Production Order). This reservation is from a stock transfer, within the plant. I cannot find the STO associated with it to delete!
Any ideas how I can delete this reservation without the STO? Or how I can find the STO? (Search in ME23n for the material, but cannot find this one - dated 9/2004)
