Error connection: The specified identity can open the document

jsobrinho — Sat, 16 Nov 2024 03:51:33 GMT

Hi Guys,

Could you please, help me? I am trying to connect by qvp Server on Nprinting, I would like to connect without putting my qvw file in File > Open File > File.qvw

I have a new folder where is the File.qvw:

- Does not exist section access;

- The user from Nprinting server has authorization in File.qvw in QMC

- I can open the File.qvw in Nprinting server by IP and the folder path

Hi,

maybe this helps:

- Open the folder where the QlikView document is saved and right click on it.
- Choose Properties.
- Choose Security in the ribbon bar in the window that opens.
- Click on Edit and add the NPrinting Engine service user to "Group or user names".
- Give the NPrinting User full control.

Regards

First of all, thank you for your answer

The NPrinting Service user has access on the folder, Administrators group.

Hi,

Did you check the NPrinting logs ? Any error there?

BR!

Hi! Access to the folder might not be enough, are you sure that it's full control? https://support.qlik.com/articles/000045680

As an alternative, you can try and add the credentials of a different user that is able to access the document via the Access Point by checking "Connection requires authentication"

Yes, the user has Administrators grant I saw in folder properties.

Is very very strange, because when I click in Run verification I have the error, but if I reload metadata manually its OK, and I can Edit and send a report, this is very strange right?

Why run verification I have an error, but I can reload metadata and I can edit and send a report?

Hi,

log into the Qlik NPrinting Engine computer
run QlikView Desktop with the same Windows user that runs the Qlik NPrinting Engine Windows service (sift+right click and select Run as a different user)
open the .qvw that is creating issues directly in QlikView Desktop. It must work without issues.

You must solve the issues in opening the .qvw from QlikView Desktop and after also Qlik NPrinting will work.

Best Regards,

Ruggero

1) I am logged in the NPrinting server with the same service user account

2) I can open the qvw (File > Open > I putting my IP and path of qvw)

3) Reload metadata OK run verification ERROR

If the cache is generated it is ok. You will be able to use the connection in your templates.

Yes, I am using, but as I said is very very strange, because the connection reload its OK but the verification has an error, but if this it's normal and it's correct, I don't have more one problem 🙂

Thank you guys

I don't know what is causing the error in the Run Verification, but if the cache is correctly generated you should be able to use it in creating templates etc.

In case you want deeper investigate start by upgrading to latest version if you don't already did.

Best Regards,

Ruggero
