I have a requirement wherein, while saving a shipment with an output type (example ZD00), an attachment gets created and saved in the attachment list with the description "Shipment Delivery Note (ZD00)". On double clicking this attachment, we can navigate to Livelink Archive windows viewer. The output shown here will have the delivery num and material num. There can be multiple attachments in the attachment list and each attachment will have a archived document ID. My question is, how do we extract the delivery number linked to the selected attachment using the document ID?
