DPR_TS_TASK_IMP 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 "Modifiable Task Attributes" 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_DPR_TS_TASK_IMP TYPE DPR_TS_TASK_IMP.
The DPR_TS_TASK_IMP table consists of various fields, each holding specific information or linking keys about Modifiable Task Attributes data available in SAP. These include ACTUAL_FINISH (Actual Finish), COMPLETION (Percentage of Completion), CONSTRAINT_TYPE (Constraint on Start Date), START_DATE_FIX (Fixed 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. .
