Hi, Can you please anyone explain the process for reconciling GST  Annex-2 & once reconciliation completed  how oracle ERP will capture the status of the transactions like Accept, Pending, Rejected

Oracle Notes given below but not clear how it will be work:-

Overview of Form GST ANX-2:

• FORM  GST ANX-2 is an annexure to the main return FORM GST RET-1, and will  have all the details of inward supplies, for the recipient of supplies to take action by either accepting or rejecting these documents, or  marking them as pending, for action to be taken later.
• If the recipient  accepts these documents, it means that the supplies reported in such  documents by the suppliers in FORM GST ANX-1 are correct.
