E2CLACM 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 "Compilation for Classic Dependencies" 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_E2CLACM TYPE E2CLACM.
The E2CLACM table consists of various fields, each holding specific information or linking keys about Compilation for Classic Dependencies data available in SAP. These include DEPID (Internal counter for objects in an SCE knowledge base), TERMID (Internal counter for objects in an SCE knowledge base), TYPE (Character field of length 6), OPERATOR (Character Length 11)... 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. .
