MSAM10_CODEGROUP 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 "Code Group Key" 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_MSAM10_CODEGROUP TYPE MSAM10_CODEGROUP.
The MSAM10_CODEGROUP table consists of various fields, each holding specific information or linking keys about Code Group Key data available in SAP. These include CATALOG_TYPE (Catalog), CODEGROUP (Code Group), CODEGROUP_TEXT (Short Description of the Code Group)... 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. .
