Cause
Transactions with "#CheckBalance" are added to the Transactions table in order to verify if the balances match, between the one recorded in the "#CheckBalance" transaction and the one present in the accounting file. When the two balances do not match, there are mistakes.
Solutions
You need to check the records of the account with the mismatch in the balance. Correct and repeat with the "#CheckBalance" function.
