SAP MM T-codes: the working list
SAP MM is the materials management module: material and vendor data, purchasing, inventory and invoice verification. This page lists the MM transaction codes buyers, warehouse key users and consultants use most, grouped by task.

What changes in SAP S/4HANA?
In S/4HANA the business partner (BP) replaces XK01 and the other vendor master codes. MIGO replaced the old goods movement codes such as MB01, MB1A, MB1B and MB1C, while MB51, MB52 and MMBE remain. ME21N, MIRO and the purchase order lists still work. Public cloud uses Fiori apps only.
38 codes. Any code's title can be checked in the system itself with SE93.
