Layers in D365

(1) ShareShare
ReportReport
Posted on by Pete Alberts 3,542

I have never worked in AX2012 - I started with D365. The company I work at still does a lot of work in AX2012, so I hear a lot of layers and overlaying and whatever.

At the moment I simply ignore layers - I just think in terms of packages and models. But layers are still there - the model I work on is in the ISV and most of the baseline elements I use are in SYS.

  • What relevance does the layer an element resides in have?
  • What relevance does the layer a model resides in have?
  • Are layers something I should look into for development in D365 or is it of negligible importance?

Thanks for reading

    Hi Pete,

    You can ignore the layers in D365. It is now more a tag who created a model with application objects. In AX2012 it was possible to overlayer objects. Then the layers were evaluated in a specific order. As we now can only use extensions, all application changes are working next to each other. There are some restrictions on how to do the coding, but taking this into account, there are no options were some code was hidden due to an overlayered object.

    Note that overlayering is still possible in application versions lower than 8, but they'll become unsupported in a few years and from that point overlayering (and the purpose of layers) will be really gone.
