SM30, change standard width of Tablecontrol

One thing that always bothered me with the Table Maintenance Generator is that when we create a Dialog for a table with many fields the Table Control always show a width of 80 columns, even when the screen has space to show more content.

Wouldn’t be great if we could harness this lost space?

Well, you can say, there is a simple fix for this. We can manually change the width of the Table Control, but the problem with this approach is that when the Generator is executed again (because a field was added to the table for example), the Table Control returns to the 80 columns layout.

With the solution proposed below, every time that the table is called in SM30, if the width is less than the desired the code kicks in and resizes the Table Control.

Solution:

Call the function to change it in the initialization event of the program using “Events” and pass to it the desired width of the Table Control. If the Table control and the enclosing canvas is less than the value passed the function change the width and re-generate the Dialog screen.

In the Table Maintenance Generator select the menu below:

Add the event 19, “after initializing global variables, field symbols, etc.” for events reference see http://help.sap.com/saphelp_nw70/helpdata/en/91/ca9f0ea9d111d1a5690000e82deaaa/content.htm

Call the function passing, the maintenance table, maintenance function group, dynpro number and desired width.

And that’s about it, see ya!
