PRP_TS_RESOURCE_TASK 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 "Tasks in Which a Resource Was Involved" 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_PRP_TS_RESOURCE_TASK TYPE PRP_TS_RESOURCE_TASK.
The PRP_TS_RESOURCE_TASK table consists of various fields, each holding specific information or linking keys about Tasks in Which a Resource Was Involved data available in SAP. These include PROJECT_GUID (Application Object GUID (Entity with Conversion Exit)), TASK_ID (Task Number), SORT_NUMBER (Sort Number), PLANSTART (Planned start date)... 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. .
