By default, both
the values specified in material_assign.cfg and the custom
set values of the table are shown in the combobox list.
If you want to exclude the custom set values of the table for specified database fields, do the following:
1. USERDIALOG_SKIPDBLOAD=MAT_NAME -> The "Material" combobox is only filled with the config values. Table values are ignored.
2. USERDIALOG_SKIPDBLOAD=MAT_NAME,LOC1 -> The "Material" and the "Location 1" comboboxes are only filled with the config values. Table values are ignored.
