Print manufacture parts pdf when printing job traveler

We are wanting to print all the engineering pdfs that are attached to parts. I am able to get an APR that will print all attachments from the part table but I can’t figure out how to make APR ignore purchase parts. Currently, we are passing Partnum and part type to DocStar. I am using JobHead as the break table and have a “Take ECM Attach” that looks at the JobAsmbl part number and pulls the drawing correctly and then another “Take ECM Attach” that looks at JobMtl part number and pull the drawing for them but it is pulling purchasing parts which we do not need for the job traveler. Any idea would be greatly appreciated. Thanks.
