There are 4 Table-Types within the SAP System:

1. Tables which have technical control functions within the SAP system. They are maintained either by SAP or by users with special authorization.
2. Other tables contain basic commercial data (bank data, currency …).
3. Tables for the organization of a company (company codes, customer data …).
4. And last but not least there are tables for application data, which contain business transactions and master data and are processed using SAP programs.

An overview of the most important SAP Tables for all these categories, as well as the necessary SAP Transaction Codes - Tips & Tricks to maintain them, are provided on the linked pages.
