ME28 release PO and it it blocked and not release
I need your assistance with the following issue:
Working with Tcode ME28 to approve a group of PO´s it is approved. but after a while all the previous changes are rollback and all became not approved.--> release indicator - blocked
They have used ME28 to release the PO. They say, it shows that the documents are released, but later when they verify the document, it is still blocked. Is there any reason why this is happening, other than human error
No other changes are shown (if any) in these tables CDHDR. My guess was that the user did not save the document properly, but the user claimed, the same thing happened for the same document for around three times.
Any ideas what the issue could be?
