MtlTags - Inspection Process - Serial Numbers

We need to print the serial numbers on the mtltags (pass/fail) from the Inspection Processing Entry screen. I have copied the original MtlTags RDD and added RcvDtl and Serial No - Created the links and modified the SSRS with no success.
Usually I create a BAQ first to test the data (our database is not on prem), but the MtlTags table is not available for me to use, I’m not sure how to proceed.
Is there anyone out there printing Serial Numbers on PASS/FAIL tags?

What does your Join look like between RcvDtl and SerialNo?
