MAEBR 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 "Display Structure for Worklist EBR (Workplace)" 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_MAEBR TYPE MAEBR.
The MAEBR table consists of various fields, each holding specific information or linking keys about Display Structure for Worklist EBR (Workplace) data available in SAP. These include MATNR (Material Number), WERKS (Plant), OBJECT_PROD (Icon: Not All Order Objects Are Completed), OBJECT_QUAL (Icon: Not All QM Objects Are Completed)... 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. .
