MM - Purchasing Master Table
Understanding table relations is essential, especially when you use ABAP for updating tables. You need to familiarize yourself with the table names too. For example, in SAP MM Purchasing, the basic master tables are MAKT (Material Description), MARA (Material Master), and MARM (Units of Measure). The relations between tables explain the dependancies of tables in the same module (in MM only) and across different modules (with FI for example). So, happy exploring the tables !
