The integration between Access Supply Chain and Access Capture works differently to how the standard integration between Dimensions and Access Capture works. It is normally installed as a set of services which send data (such as Purchase Order Lines) to Access Capture.
When you then upload a Invoice to Access Capture, it triggers an 'Extraction' process which Access Capture software, validates and extracts the invoice data based on it's learning capabilities and software code.
If the extraction process was not able to identify where on the Invoice image the PO lines exist, then you may not have a full 'suggested' field values in the PO lines for the Invoice.
Then when you click on the magnifier button, you are in fact, loading the 'Imported' PO lines data from your Access Supply Chain software.
By selecting the line(s) from this window (Search purchase order lines) you would not expect it to populate the Quantity, Unit Price or Total Value of the Invoice PO Lines, as this would need to be manually entered, or would have already been populated from the 'extraction' process which happened at the time you uploaded the Invoice to Capture.
Selecting a PO line from Search purchase order lines does not populate the Invoice Line Quantities, etc (Access Supply Chain)
