Back to this broken record. But I may have found the pot of gold at the end of the rainbow. It appears that quality control standards are not in play in the programming department, Added a UDF (linked to UDT) to the SO Header and SO Invoice Header panels. UDF's are nearly identical. The magnifying glass appeared on the first try (with a message that the UDF height had to be one) on the SO Order header but I gave up after five tries at getting the same behavior on the SO Invoice header panel. As I was typing this note, I realized that the only difference was **that the Order UDF is a manual entry and the SO invoice UDF is a BOI link.** So I created an invoice UDF as a manual entry validated against the UDT, then added that test UDF to the Invoice Header panel. Viola! The magnifying glass look up appeared. I then deleted the original UDF and recreated as a manual entry. Added that to the Invoice Header panel and EUREKA! The magnifying glass appeared. Success. I then modified the UDF by linking it to the SO UDF as done originally. Wow, 9:30 AM and it is High Satisfaction Day already.....
