To obtain values from MASTER table fields you have to use the FlowHeater default value property for this field like the screenshot below.
Here you can choice all fields from the MASTER table, or enter a custom value of course. In case the MASTER field is an “auto increment” field FlowHeater knows the new ID and use the right one.
There´s just one problem. To detect whether an insert or update should perform you need another criteria instead of “CustID” in the Master table! In the screenshot I switched the Primary Key manualy from “CustID” to “CustName”.
