Invoice Approval Re triggered after payment is voided.

Hi Guys,

Have a question, currently in our production environment, when we have done payment VOID, invoice approval re triggered. Can someone tell me, if invoice is already approved and payment is voided, invoice approval should not have been re triggered right, it should automatically eligible for next payment or user should be able to cancel the invoice. Is there any setup or anything that might have caused invoice approval to re trigger.? I did look at the ap_invoice_lines_all and ap_invoice_distributions_all table nothing got changed. Only last_update_date and last_udpated_by on ap_invoice_lines_all got updated but amounts and rest of the column looked unchanged.
