I have had various problems with the grid changes but here is one I can reproduce.
I was trying to change CONV_TYP_ID from 1 to 0.
As you can see there is not much info in the trace file.
I have tried it on ASE 12.5.3 and ASE 15.5.
The Error posting changes is not always displayed but as far as I can see the update is never done.
