AR - Standard Receipt Entry

Hi,

I have entered an invoice which has GST of 6% thru Standard Invoice Entry. The following are the double entry:

Dr. Trade Receivables   31,800

Cr. Output Tax Acct        1,800

Cr. Income                   30,000

Upon receipt, there is a bank charges of 100 incurred. The following are the AR Receipt screen:

We noted the following double entries captured when the AR receipt post to GL:

The system will auto calculate the GST tax for the bank charges incurred based on the same tax code applied to the invoice matched.

Should this is standard JDE feature and if yes, where is the setup to check for this? Any way to disable the GST compute for the bank charges ?
