PSFC_HEAD is a standard SAP Structure so does not store data like a database table does. It can be used to define the fields of other actual tables or to process "Header Information for PSFC Layout Sets" 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. i.e. DATA: wa_PSFC_HEAD TYPE PSFC_HEAD.
The PSFC_HEAD table consists of various fields, each holding specific information or linking keys about Header Information for PSFC Layout Sets data available in SAP. These include AUFTEXT (Description), AUARTTXT (Text, 40 Characters Long), MATTEXT (Character field of length 40), DSNAM (Name of MRP controller)... See below for full list along with technical details, documentation, text table, check tables, foreign key relationships, conversion routines, relevant tcodes and example ABAP select code etc. .
