Custom Field use CF$ to join in same view

Hello,

I need Advice on how to solve this,

I am trying to get this custom field to work. It is a Read Only Custom Field. The syntax is validated successfully. But when I publish I get “ORA-01403: no data found” (see server error message below). The event  looks like this:

I need to use part_no and price_catalog_no to join. Price_catalog_no was not available in the lines only in the header. That is why I created this custom field. This cf works as intended.

I am using price_catalog_no from here as a join. 

Server error messages:
1732c290-72d8-4b97-83c9-929e0d69c15b
