Ignore Item on TO picklist creation

I've been having a problem with TO picklist.

I need to ignore some items when I'm creating the TO.

I change the program SAPML03T (enhancement point) to check the item and the logic delete, on TAP table,  the items that I don't want to on the TO list. But when the function L_TO_CREATE_INT is called all items that I deleted on the enhancement point turns back.

I checked theFunction Group XLTO to check the function exit to chance it. And I can't find a place to do that.

I tried to use the MWMTO012 enhancement and it's not working.

Just to illustrate:

E.g: I have 3 lines on TAP table and I want to delete 2 lines. But I need to find a way after the L_TO_CREATE_INT since the lines comes back if I delete it before it.

I'm using the VL06P to create the TO.

Thanks a million,
