I think it depends on which database your Dynamics Nav is installed on. The database could be Dynamics Nav's own format. If that is the case you need to connect through an ODBC-connection, first installing Navisions own ODBC-client. Be aware that the ODBC-client will use one of your businessusers license, so you might need to purchase another. I'm not aware if their own format has been discarded or is still in use, so please forgive me if my suggestion is needless...
If your Dynamics Nav runs on SQL-server 2005 then of course you should do as suggested by Karl Pover :-)
I intend to use NAV with SQL Server. But the right question it isn't only to refer to link simply to the underlying db. Other vendors offer NAV accelerator, to simplify and facilitate integration between QlikView and NAV at ETL level and at model data level. In few clicks it is possible to load data into a multidimensional structure built following best-practice dataware housing criterias.
Now, does QlikView offer a similar integration with Dynamics NAV?
Ok, you are looking for what QV calls a template which is a QV application like any other that contains the load script made to extract the most important tables from a certain ERP and contains a series of general reports to get started quickly.
I haven't seen a template for NAV in the community. I've seen plenty for SAP. I would repost your question and ask for a Dynamics NAV QlikView Template to see if anybody has one.
there is another NAV Connector "NAV2QLIK" for QlikView from QlikView Solution Provider prisma informatik GmbH located in Germany.
"The preparation and connection of ERP data from Microsoft Dynamics NAV into QlikView usually means a tedious and time consuming task to end users.
To simplify this process and to reduce the preparatory work to a minimum, prisma informatik has developed the NAV2Qlik Toolbox. On the part of users, neither profound QlikView knowledge nor elaborate support by the internal IT department is necessary during the ETL process. The NAV2Qlik Toolbox comes with the N2Q Script Generator, which generates the required QlikView Scripts for data modeling automatically. Further components are the N2Q Grouping Function and the N2Q Templates, which provide various options for interface design in QlikView.
Especially the customizations within their ERP data are particularly valuable for users of BI software. For this reason and unlike other connector solutions, NAV2Qlik delivers no pre-built script, but can generate the QlikView data model automatically direct from the specific NAV environment. That way, NAV2Qlik enables the transfer of any custom-built extensions and modifications within Microsoft Dynamics NAV - no matter how individualized the database is. A separate number range without modifying standard objects allows a conflict-free integration into the ERP environment."
