We have a business scenario:
Currently we are generating one post-shipment document for each pre-shipment document. But the business wants to first generate post-shipment documents for each pre-shipment document and then club all post-shipment documents for a single consignment, together to generate a final post-shipment document with different EXP number. This final document we need to print. How can we club several post-shipment docs into one post-shipment doc?
