PSMLSTD_CONTEXT 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 "Context for Current WBS Element" 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_PSMLSTD_CONTEXT TYPE PSMLSTD_CONTEXT.
The PSMLSTD_CONTEXT table consists of various fields, each holding specific information or linking keys about Context for Current WBS Element data available in SAP. These include CREATE (Ind.: Authorization exists), CHANGE (Ind.: Authorization exists), DISPLAY (Ind.: Authorization exists), ACTDATES (Ind.: Authorization exists)... 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. .
