CMT_OBJ 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 "Objects for CO Commitment" 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_CMT_OBJ TYPE CMT_OBJ.
The CMT_OBJ table consists of various fields, each holding specific information or linking keys about Objects for CO Commitment data available in SAP. These include POS (5 Character Numeric NUMC), INFO (Natural Number), CCTR (Single-Character Indicator), ORD (Single-Character Indicator)... 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. .
