Hi, @kkraus !
I don’t think changing the control type of the field will be what’s needed in this case.
The order type field uses the PXSelector control which is used to select a key value from a record saved in the database, whereas the dropdown list is typically used for a list of values predefined in code.
You probably need to look at using the PXRestrictor attribute similar to what’s mentioned in this article.
Conditional PXRestrictor on Look up | Community
The PXRestrictor allows you to restrict the values available for selection in the selector control based on the conditions you specify.
In technical terms, it adds a “WHERE” condition to the SQL query that is generated to select the available values for the Selector control.
Does this make sense?
