LK01 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 "WM communication record 1" 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_LK01 TYPE LK01.

The LK01 table consists of various fields, each holding specific information or linking keys about WM communication record 1 data available in SAP. These include SAKOM (Type of communication record), LGNUM (Warehouse Number / Warehouse Complex), TBNUM (Transfer Requirement Number), TBPOS (Transfer Requirement Item)..
