Alright. This one is solved.
This is the message that I am referring to:
Thanks to David; his comments really eased my troubleshooting. But then, I still had to delete each product from the DYNAMICS.SET file and find out which one that’s throwing this message.
The product, which throws this message, is: Grant Management
This comes under the product Analytical Accounting, as a sub-product (or sub-feature).
Now the question that comes to my mind is: For what reason this message is getting populated? Is it something really critical? Or is it just another example of a Developer’s Mistake to leave this message on the code after completing his/her Unit Testing?
Till we find an answer to that, for those who have faced this message: Just make sure that you have the DEBUG menu disabled (by setting the ScriptDebugger=FALSE statement in DEX.INI) and in case it is needed, deselect the Debug Menu Option “Show Debug Messages”.
