How to do PI?

Hi Expert,

I want to clear out stock from SAP system. So i do MIGO without referring to PO and mvt type 562. In MMBE i got 42 stocks for material A. So when i do migo, i put qty 42 but system prompt me error message "Deficit of BA Unrestricted-use 42 CON: A <plant>< sloc>< batch>"

I noticed that this material has batch assigned but when i check in MMBE, there's no batch for it. Then when i try to do PI via MI01,MI04 and MI07, it will just increase the stock. There's no mvt type 702 here.

Please can anyone tell me what is the exact process in PI step by step in order for me to make the stock for this material is 0.
