Hi, this will not work as one receipt can contain more then one purchase order. Can you explain the business need why do you need to see on receipt PO number if the same information can be seen already from PO directly?

Our receipts will never contain more than 1 PO per receipt. I figured you could do an automatic link and specify the line to grab the first PO number. 

The index for PRECEIPTD is the PTDNUM and the receipt line number. You can specify the line number to 1000 to always pick the first receipt line. 

I would do something similar to below. Even though PRECEIPTD may already be on the PTH object, I would not mess with it since it's part of the standard. I would add another line of PRECEIPTD and give it a ZPTD abbreviation

Then on the selection tab, instead of referencing the table, use the expression to reference your ZPTD table and field

I hope this helps

Thank you Mike! This worked perfectly 

I'm using this discussion as a reference for something very similar.  I'm trying to pull information from either the SINVOICED or SINVOICEV table. I have it all setup, but the value is always <empty>.  I know there is data that could be displayed, it's just not fetching it or displaying it, and I'm not sure why.  Any thoughts?

I've added line 2 & 3 to the DU6 object:

Then I added this to the selection screen:
