KPP1LDEP 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 "Dependencies: Attributes for Value Columns" 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_KPP1LDEP TYPE KPP1LDEP.
The KPP1LDEP table consists of various fields, each holding specific information or linking keys about Dependencies: Attributes for Value Columns data available in SAP. These include A_CONT (Field Contents of Cell in Logical Screen), A_ROW (Row in Screen Area), A_COL (Column Item Within Screen Area), A_ACTIVE (Ind.: planning dimension for display active?)... 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. .
