Cannot adjust "Bank Charge" with Type = Line on Adjust Receipt Form

 Hi everyone,

I don't understand why sometimes I cannot adjust "Bank Charge" in the Receipt Adjustment Form. It said "APP-AR-11091: You cannot over apply this transaction"

1. I have transaction (have vat item)

e.g invoice 970

      vat         30

      total    1000

and receipt 998, (bank charge = 2)

On Adjust Form, I entered Activity as Bank Charge, Type = Line and Amount = -2 but the I got the error " APP-AR-11091: You cannot over apply this transaction"

Then I changed the Type to Invoice then I can enter the Amount = -2 .. didn't get the error.

2. I have transaction (no vat)

e.g invoice 1000

and receipt = 998 (bank charge = 2)

I can adjust with the Activity as Bank Charge , Type = Line and Amount = -2 without any error.
