Hi Larry
Actually our flow is 3.5 and even in the update rules, its perfectly working fine. The earlier screenshot that I shared was from another cube to 0PUR_C01. Just for testing purpose, I changed the rules of 0COUNTRY and it worked.
In the update rules, it appears like this, I tried changing it and it works fine. No dumps, no issues
As you are using infosource, try to use the transformation from infosource to cube for this purpose. You could leave the 0COUNTRY field blank in the transformation between DS and IS.
As we are not sure of what is the real cause for this, we could just try different things in trial and error basis. After all, we need the transformation to be active. So give a try
