Just thought to do a quick post on the posting errors which I encountered in Projects Module. (Posting Hours Journal)
On posting Hours Journal in Project Module, I stumbled upon this error "Invalid Dimension Validation Error"
I knew it would be some setup which is missing, but bit time consuming to go to each setup and look where what went missing, so straight away went into debugging mode :)
a. The code below checks whether Dimension has been set for the employee.
b. Once this was set, the error vanished.
