Kindly check the below Documented KBA:
2304535 - BAPI_GOODSMVT_CREATE - GMCODE for MIGO in table T158G - SAP ERP & S/4 HANA
..............
The entries in table T158G are just program-internal keys, which stay in place, even after the MB transactions become obsolete. The BAPI_GOODSMVT_CREATE does not call any transaction.

So, this is just an internal naming and standard system design.
