When I tried to look up an JD Edwards data table residing on a AS/400, I encountered the error message:
"An external lookup data source.... is either missing or invalid.........."
The issue is the table does exist, and the data fields I used for linking are of the same type and length. I could not figure out why Monarch could not find the table. I used the same ODBC in another Monarch model and it worked fine and is still working fine.
Thank in advance for any advice.
