SPFYTAB SAP System parameters: Buffer, memory, processes Structure and data

SPFYTAB is an SAP Structure so does not store data like a database table does but can be used to process "System parameters: Buffer, memory, processes" Information within sap ABAP programs. This is done by declaring abap internal tables, work areas or database tables based on this Structure. These can then be used to store and process the required data appropriately.


Below is the documentation avaialable and full details of the fields which make up this Structure.

You can view further information about this via relevant transactions such as SE11 or SE80. Also check out the Comments section below to view or add related contributions and example screen shots.
