I ran into an issue today I've never noted before. I was trying to figure out why the budget in an FRx P&L report didn't match the budget figures in my Excel budget file. After a short amount of investigation, I realized that not all the accounts in my Excel budget file were setup in GP. However, I received no type of error message when importing the budget that the accounts were missing. Apparently, when GP encounters accounts in an Excel budget import that don't exist in GP, it just skips over them without any indication of such.
Something to keep in mind when importing budgets . . .
