CMS_STR_OBJ_SKY 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 "Object Semantic 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_CMS_STR_OBJ_SKY TYPE CMS_STR_OBJ_SKY.
The CMS_STR_OBJ_SKY table consists of various fields, each holding specific information or linking keys about Object Semantic Key data available in SAP. These include OBJECT_REF_ID (Reference ID for the object), SUBOBJECT_REF_ID (Reference ID for the Sub-object)... 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. .
