>It is very strange, indeed. What if you create CuDed1Emp with Readwrite command instead of Nofilter?

I create it with NOFILTER and READWRITE.
I tried creating it only with READWRITE and got the same result.

I wonder if it has to do with how the cursor is created? It has a GROUP BY clause. I will test this idea...

No, it is not related to the GROUP BY clause because I removed the GROUP BY clause and received the same error.
