CSKRU 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 "Ambiguity Indicator for CSKRF" 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_CSKRU TYPE CSKRU.
The CSKRU table consists of various fields, each holding specific information or linking keys about Ambiguity Indicator for CSKRF data available in SAP. These include REINHUNI (Unique ind. for fields in RK master data (used internally)), WERKSUNI (Unique ind. for fields in RK master data (used internally)), MATNRUNI (Unique ind. for fields in RK master data (used internally)), EXTNRUNI (Unique ind. for fields in RK master data (used internally))...
