SAP NAST_MSG Message Table data and field list

NAST_MSG 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 "Message" 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_NAST_MSG TYPE NAST_MSG.

The NAST_MSG table consists of various fields, each holding specific information or linking keys about Message data available in SAP. These include MSGTY (Message Type), MSGNR (Message number), MSGV1 (Message Variable), MSGV2 (Message Variable)... 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. .

How do I retrieve data from SAP structure NAST_MSG using ABAP code?
