COMT_PR_ORG 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 "Identification of an Organizational Unit with Description" 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_COMT_PR_ORG TYPE COMT_PR_ORG.
The COMT_PR_ORG table consists of various fields, each holding specific information or linking keys about Identification of an Organizational Unit with Description data available in SAP. These include PR_ORG_TYPE (Indicator for Organizational Dependency), PR_ORG_ID (Identification of an Organizational Unit), PR_ORG_ID_DESC (Organizational Unit Description)... 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. .
