Manual adjustment of gst amount

Hi… Am trying to use the purchase journal for posting a transaction with the gst amount, and i need to maually adjust the bal gst amount by for eg by one cent. I am working on the Navision attain version 3.60. The setup i have done for allowing manual adjustment. In the General ledger - -checked the PMT Disc Excl GST -GST Tolerance % made it to 100 Journal Templates Checked the allow Gst Difference Purchases and payables setup Checked the allow gst difference After doing all the above I still get an error message The Bal gst difference must not be more than 0. Is there any setup that is being missed here. Please advise … Thanks and regards Ramanan --------------------------------------- moved from Technical Forum by moderator
