CMS_STR_PCN_CR_DB 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 "Change Request Data: DB Layer" 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_CMS_STR_PCN_CR_DB TYPE CMS_STR_PCN_CR_DB.
The CMS_STR_PCN_CR_DB table consists of various fields, each holding specific information or linking keys about Change Request Data: DB Layer data available in SAP. These include CR_GUID (Change Request Primary Key), PROC_OBJ (Process Object), OBJECT_ID (Object Identifier of Change Request), INT_STATUS (Change Request Internal Status)... 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. .
