10.3.3 Changing the INITIALIZE Method
Now, you have to make some changes in the INITIALIZE method, as shown in
Listing 10.25, to accommodate the facts that (a) you now have a container being
passed in and (b) you want to add some user commands programmatically
The table of user commands is passed in from the calling program via the CREATE_
CONTAINER_PREP_DISPLAY method, which fills up global table MT_USER_COMMANDS
before calling the function module.
In the FILL_CONTAINER_CONTENT method, this table is passed into the
DISPLAY_DATA method, which in turn calls the INITIALIZE method.
PREPARE_
Exhausted after all this travel, the table of user commands finally arrives inside
the INITIALIZE method in the form of importing parameter table IT_USER_COM-
MANDS.
In Listing 10.25, if you have a container, then the factory method of CL_SALV_
TABLE is called, this time passing in the container object. Next, the program has
to specifically ask for the basic toolbar to appear at the top of the screen; SALV
will not do this automatically.
