Hi Jurgen,
I' already check SLDE SAP posted the document, it is post by calculate by total shelf life field , not use the expiration date that I manual key when GR
Example , Total shelf life is 365 days
In screen migo I enter the MFG date to 2.02.2014 and enter SLED date to 2.01.2015 , But when check the document system show warning message "Existing SLED &Date has been changed to &Date by the program" and when I posted document I check on the batch master for material by MSC3N I found the date SAP posted is 2.02.2015. It is calculate by total shelf life not use input from MIGO screen.
