Hello All,

I have a requirement that on saving an Outbound Delivery(VL02N), an Outbound Idoc should be posted...but the condtion for posting the idoc should be its shipping point. I am not sure how to configure shipping point as the trigger point for the idoc.

Please suggest.

Thanks for your co-operation.
