It’s so nice to meet you in this virtual platform where we’re here to help
each other in resolving issues.
As far as I’ve understood, the last value you’re trying to update is
0(Zero) where as the acronym column only accepts character or
characters with number(only 2). I’d rather suggest you to try to give an
update like A0, 1B, 0C.
Hope my inputs will come to your help. It’s our pleasure to help you in resolving issues. Keep me posted!
