When supplier is doing an Outbound delivery (VL01N), and PGI for a ASN, at what stage will the ASN will be sent to customer, will this be after creation of delivery not after PGI am i right?, if so which document i need to config the message determination to generate the IDOC.
The ASN will be ideally generated during OBD creation since the customer has to account for the confirmation/incoming receipt. Typically, LAVA is the output type used in OBD's since the processing routines are set at EDI or ALE. This is as for the general output set up is concerned. Subsequently, you have to make necessary set up in partner profile to enable the message type DESADV for the customer partner to be able to transmit the ASN.
