Tip #1154: When Unified Interface misbehaves

We know that Unified Interface is not yet on par with the classic UI. Some things are not yet there, some things will never be there because there are better ways to achieve the same results.

Since Dynamics 365 is a continuously updated beast, sometimes bugs and inconsistencies make their way into a working feature. The other day I was asked by Brent “I am a little afraid of what’s to come” Howard why, after the latest update for the Unified Interface (1.3.230-180801-000211) has removed the ability for users to Associate records in a N:N relationship. (To qualify: not just any relationships but the ones that involve contacts – t.j.). The workaround is for the user to switch out of the Unified Interface and use the classic UI however most of their work force are using the mobile interface and are only very basic PC users.


When you add N:N relationship between an account and a custom entity, say, foo, and then add a subgrid to the account form, the menu looks like this:

N:N grid with Add Existing

That allows to associate an existing Foo record and create a new one if needed (association side panel has a +New button).

If you add a new N:N relationship between account and contact entity then subgrid menu will look like this:

N:N grid without Add Existing

Note that Add Existing is just not there.


Kudos to Brett for finding the workaround that involves, you guessed it, poking around with the Ribbon Workbench.

  1. Create a small solution that includes contact entity and application ribbons.
  2. Open either standalone Ribbon Workbench or as part of the XrmToolBox and load that solution
  3. On the SubGrid ribbon you’ll find two Add Existing {0} buttons, select one with the Id of Mscrm.SubGrid.contact.AddExistingAssoc
  4. It’s a system button so nothing will show up until you right mouse click and select Customise Command (note that Scott is from UK and sneaked in correct spelling of the word Customise)
    Customise command for system button
  5. That will light up Solution Elements panel where you’ll find Mscrm.NotUci enable rule. The rule looks like this
    The rule that removes the Add Existing button
  6. Right click > Delete (you do have a backup, don’t you?)
    Delete the enable rule
  7. Publish the solution, then reload the form and here we go:
    N:N contact grid with Add Existing command

If I have to guess, the regression bug is in Xrm.Internal.isUci function from the Marketing/ClientCommon/Marketing_ClientCommon.js web resource but let’s wait and see how it’s going to be fixed.

    What can be done, if both are custom entities, having N:N relation ship, add existing button not visible in subgrid,

  2. Yen says:

    Hi – I can’t see my N:N relationship from the ‘Related’ option – is this an expected behaviour? Both entities are custom and they work from the subgrid.
