COOBJ_SENDER_FLAGS 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 "Sender: Possible Fields in Posting Variant" 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_COOBJ_SENDER_FLAGS TYPE COOBJ_SENDER_FLAGS.
The COOBJ_SENDER_FLAGS table consists of various fields, each holding specific information or linking keys about Sender: Possible Fields in Posting Variant data available in SAP. These include XS_LSTAR (Show activity type), XS_AUFNR (Show order), XS_AFPOS (Show order item), XS_VORNR_AUF (Show Order Operation)... 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. .
