RE: DICITINARY NOT LOADED FOR TRANSACTION ENTRY LOOK UP
Pat is the user attempting to run a report? This is the most common place for this to happen.
This would suggest that the Launch File is pointing to a different location for one or more dictionaries.
Suggest that if you are comfortable with looking at the local copy of the DEX.ini file - open the file ( text editor ) and see that the location of the dictionaries all agree.
Another option is to ensure that the user has access - SECURITY - to the location where the dictionary is located. The user may not have folder access required by Microsoft Dynamics to open / access a dictionary. This can happen on the local machine as well as a network location. Make sure that the user has Read / Write / Delete / Modify ( not sure if that is all - but do not require ALL or SPECIAL )
Hope this helps.
