In Ax2012 R2, I create an intercompany transaction for purchase order and sales order. Purchase order is from marketing company and sales order raise in manufacturing company.
Is there any setting in ax2012 that I can post the sales order packing slip (manufacturing company) and it automatic post the purchase order GRN (marketing company)?
I do not need to manually post the GRN in the marketing company.
Not sure about packing slip posting, but invoices can be posted automatically. Check out the inter company trade setup for the vendor/customer on the vendor customer master. You can define the parameter on intercompany setup (General tab)
