Question: Why am I getting this error popup, “This GL Entry will cause an out of balance and cannot be completed. Please modify your edits and try again.”
The GL entry you are trying to create will lead to an Unbalanced Balance Sheet. This is most commonly seen when making manual journal entries to Bank GLs. Bank account GL's are system-maintained GLs. Since the user is only creating a GL Entry to the bank account, it won't create the bank register item, thus putting your Bank Register out of balance with your Balance Sheet. Vantaca is trying to prevent your association from having an out-of-balance down the line by giving you that error.
Instead of a manual GL Entry, you can process post-deposit, post-expense, or transfer funds through the appropriate screen. This will create the necessary bank register item, as well as have the GL impact you need and you'll be able to reconcile.
