Cannot Build Project due to missing reference

Posted on by Michael Morin

Hi,

I am a beginner to development in AX 7. So I apologize if this is something I should know. I wanted to create an entity to extract some data from AX 7. I created a solution and project and then added an entity using the Wizard. I wanted to start simple so I added the InvenTable and EcoResProduct.

When I build the project I get the following error:

Error A reference to 'Dynamics.AX.Ledger, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' is required to compile this module.

Now I did some digging and see that I could import some of the references under C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions. Most of the references referred to in the warnings are there, however the Dynamics.AX.Ledger, from the error, is not.

Did i miss installing some library?

Thanks in Advance

Michael Morin

Hi Gopal,

You need to update your model parameters and add a reference to ' ContactPerson ' package.

Hi Andre,

I faced exactly same error while i was creating a custom entity to export released products along with some additional fields from products. Your suggestion helped me here, in my case a 'Currency' package was missing. I have referred that and error went out. Thanks!

That was exactly it. Under the model references there was a Ledger option. I checked it and everything builds.

Thank for you help.

Hi Michael,

You need to check how you created your model. In this case you would need to have an extension model and add more referenced models. I guess a ledger model should be referenced.

Using the Dynamic AX menu in VS you can update the model properties to add models as reference.
