To determine whether an ASN has been received at one of Mochila's warehouses, you can search for the ASN using the portal under INVENTORY --> SEARCH INBOUND SHIPMENTS.
Search for the specific ASN you are looking for under the Inbound Shipment ID.
If the ASN has been received, you will notice both the units received as well as the date it was received. In addition, clicking on the ASN ID will take you to the ASN detail page which will list all the items in the ASN, the expected and actual received quantities as well as any variances.
