I'm currently importing a relatively large number of projects and sub projects. The format I'm using for the sub projects should be -EM or -TS. However, when I try to do this I get an error stating "Only the main project id can be specified manually".
I get this message when creating sub projects through the client as well but it still lets me create the sub project. A few questions.
Does manually setting the sub project id cause issues further down the line?
If manually setting the sub project doesn't prevent the record from validating or inserting shouldn't it be a warning not an error? (The data import tool I'm using doesn't commit the transaction if an error is thrown but will on warnings)
If I do want to manually set my sub project id format to be two letters that aren't automatically assigned, what setup does this require?
