MSSLOCK7 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 "MS SQL Server lock monitor" 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_MSSLOCK7 TYPE MSSLOCK7.
The MSSLOCK7 table consists of various fields, each holding specific information or linking keys about MS SQL Server lock monitor data available in SAP.
