Use Data Director with NAV 5

How can i use Data Director with NAV 5

The same way you use it with NAV 4. I suggest to read the LS Retail manual on how to setup data director.

But this manual just for installation

Well setting it up is really the main part. Once its setup and running, using it is pretty siple.

It might be best if you just let us know what you are having problems with.
