There is a difference in amount between Credit Memo and Customer Invoice. For Example:

Credit Memo - BBB Total Amount - 168

When, you create a Follow-Up document then the system calculates Tax Amount and Tax Base Amount. In this case, the Tax Amount is zero, but there is a small difference on Tax Base Amount. This leads to error in the backend and system do not create Journal Entry.
