When using Jet Reports to access a data source for Dynamics NAV 2009R2 or earlier, the following error is displayed:
Complete text of error message is:
Internal error 1407 in module 19.
This error is most often a permissions issue in the NAV database. It is often seen when accessing a table via the Jet Excel Add-In where the user has permission in NAV to access the table for one company but not another company..
Note: Errors in Module 19 are C/Front errors. They can be looked up in a supporting C/Front file called “DBERROR.txt” which resides in the C/Front program files folder.
C/Front is the NAV utility which handles communications between NAV and other applications.
A Dynamics NAV administrator will need to assign read permissions for the table being queried to the user whose credentials are being used to connect to the database.
