Event AA: Instead of the Standard Data Read Routine 
This event occurs when the data to be maintained is read in. A different logic from the standard can now run, for example:
To read additional data
To change the data read in
To read data differently than in the standard, with extra checks
NoteThe views or table/text table data must be read into the internal table TOTAL.
End of the note.
Process
Execution
The generated read routines can be called, or used as a template for the realization of the user routines:
Maintenance dialog based on a view FORM GET_DATA_<viewname>
Maintenance dialog based on a table FORM TABLE_GET_DATA
For example to read in additional data, you can first call the appropriate standard routine, and then read the remaining data into user internal tables.
