The image viewer does not show the image in A3

If the invoice image does not appear when you open the Ubyquo document viewer from A3ECO/A3CON, you need to check the company setup, the access credentials and the viewer's error logs.

Follow these steps to identify and solve the problem.

Step 1: Check the company connections

Check that the companies and fiscal years are correctly connected in Ubyquo.

• Open Ubyquo.
• Go to Gestionar carpetas (Manage folders).
• Review the connected companies and fiscal years.

Important: No two fiscal years may be connected to the same data path.

Check for duplicate paths

• Use the ruta de datos (data path) filter to find possible duplicates.
• Check whether two fiscal years are connected to the same path.
• If you find a conflict, fix the setup so that each fiscal year has its own path assigned.

Once you have reviewed the connections, check again whether the viewer now shows the image correctly.

Step 2: Delete the viewer's saved credentials

If the connection paths are correct, check whether the problem is related to the saved credentials.

Renew the access credentials

• From A3ECO/A3CON, press F11 to open the Ubyquo viewer, even if the image is not displayed.
• In the login window, select Opciones de acceso (Access options).
• Turn off the options:
• — Recordar usuario (Remember user)
• — Recordar contraseña (Remember password)
• Close the viewer.
• Open it again with F11.
• Enter your Ubyquo user and password manually.

This process lets you authenticate again without using the credentials saved earlier.

Step 3: Review the error logs in YALV

If the viewer still does not show the image, you can check the error logs with the YALV.exe tool.

Open the YALV tool

• Go to the customer installation folder: \\Quantyca\Ubyquo\InstalacionCliente
• Find and open the file YALV.exe, used to view the error logs.

Find the log file

• Inside YALV, browse to the temp folder.

• Look for the log file named: Quantyca_Ubyquo_ErpViewer

• Open the file and check whether it contains messages related to:
• — Connection errors.
• — Invalid access paths.
• — File access problems.
• — Insufficient permissions.

The information in the log can help you identify why the viewer cannot display the document image.

Checklist

Before considering the issue resolved, make sure that:

• Each fiscal year has the correct data path assigned.
• No two fiscal years are connected to the same path.
• The viewer's credentials have been renewed.
• The Quantyca_Ubyquo_ErpViewer error logs have been reviewed if the problem persists.
