Have the following error...Before you proceed, you’ll need to delete any adjustments you recorded manually for this filing period.
It sounds like you're trying to lodge your BAS when you see this error? If that's the case, this error is due to GST adjustment transactions made using the old version of the GST centre. If you've now upgraded to the new model, you will need to remove those transactions.
Select the magnifying glass (top right) and click Advanced Search
Select GST Adjustments and filter to the appropriate date
Open each transaction and delete it.
Go back to the GST Centre and mark the BAS as lodged.
If you are not trying to lodge your BAS or would like to discuss this further, I would encourage you to reach out to our Support Team to make sure nothing has been lost in translation.
