I received error message: The Invoice Item can only be adjusted toward zero, how can I adjust my invoice?

You are receiving this error message because of a rounding issue in the UI, you must use API callout to fix this adjustment:

Please use the article to process the invoice item adjustments:
https://knowledgecenter.zuora.com/DC_Developers/G_SOAP_API/E1_SOAP_API_Object_Reference/InvoiceItemA...

Query and create the items below via API:
-query Invoice with Tax on it
-query InvoiceItem
-query TaxationItem
-create InvoiceItemAdjustment with SourceId for TaxationItem
-create another IIA to adjust the other line item
