Integration Manager Error: Cannot Open Database “GPLIV” Requested By The Login

Microsoft Dynamics GPWe’re in the middle of large upgrade project at the moment for a client and encountered an error when trying to run an integration.

This particular integration is an Account one, which has been extended with VB Script which checks to see if the segments exist, and if not, it inserts them. When a user tried to run the integration, they get the following error:

Opening source query...
Establishing source record count...
Beginning integration...
DOC 1 ERROR: System.Data.SqlClient.SqlError: Cannot open database "GPLIV" requested by the login. The login failed.
DOC 2 ERROR: System.Data.SqlClient.SqlError: Cannot open database "GPLIV" requested by the login. The login failed.
DOC 3 ERROR: System.Data.SqlClient.SqlError: Cannot open database "GPLIV" requested by the login. The login failed.
Integration Failed
Integration Results
    3 documents were read from the source query.
    3 documents were attempted:
        0 integrated without warnings.
        0 integrated with warnings.
        3 failed to integrate.

I did some double checking and it turned out that the user who was doing the testing had two Domain accounts (one with full name and one with initial and surname) and were not using the one I had configured originally.

All of the other users I had worked with had been using Domain accounts of initial and surname, which was the one I had configured, but this particular user was using the account with their full name.

Adding this Domain user account to the database with the DYNGRP role resolved the problem.
