Custom Validation Template for Processing Rule

I have to base the processing rule on order line column = attribute3 (a dff column).

steps taken:

1. OM> setup>rules>security>Record Sets

added a new line

Record Sets:

      

Record Sets: Entity	Record Sets: Seeded?	Record Sets: Record Set	Record Sets: Short Name	Record Sets: Description	Record Sets: Based on Primary Key?
Order Line		Template Flag	TMPFLAG	Template Flag

Matched Columns for record selection :

Attribute3

--note i have order line level dff enabled which has a value Y or N .

2. ran the program - Generate Constraints Validation Packages

3. created a validation template -
