I watched a video on YouTube that showed how to call a transaction by clicking on a specific field in the ALV view, but when replicating it in my code I was unable to implement this function.
When I click on a document in the “EBELN” field nothing happens.

The issue is that the program does not produce any errors, but when I attempt to debug it by placing a breakpoint in the call transaction section, it simply skips over that part. This section is only executed when there is a double-click on the `ebeln` field, but when I double-click nothing happens.

Why is the double click not executing the ”user_command” form?

what’s wrong in my code?

In this code, I retrieve data from the ekko, cdhdr, and cdpos tables and place it into internal tables. These tables are then joined on the document number and the resulting data is stored in a final table (lt_tabela1). With this final table, I can call the ALV to display the data. Additionally, I want to set it up so that when I click on the EBELN field, it navigates to the ME23N transaction, displaying the document number that was clicked on.
