Can't remove a lookup created by this plugin in XRMToolbox

[epsracing77]

I wanted to remove the lookup created by this plugin, in D365 but when I tried to do this in the Classic Interface it threw an XML Invalid Object error!!

So not sure if this is quite ready for production deployment if we can't back out the changes. This was done using D365 9.2.22091 online (edited, sorry for any confusion)

Polymorphic Lookup Manager version 1.2022.8.4

Removing it from the Form throws this error (when saving)

Checking the download log....

System.ServiceModel.FaultException`1[Microsoft.Xrm.Sdk.OrganizationServiceFault]: The Form XML f19ade57-8a2e-4eb3-b1b8-21777aefb4fe does not conform to the required schema.

D365 9.0.2 ? So you mean OnPremise, right? I'm not sure it is even supported...

What I would try : Use XrmToolBox tool FormXml manager to remove the attribute from the form Use Polymorphic Lookup manager to delete the attribute

No, online, latest version

Sorry - it's 9.2.22091.192

I'll give your suggestion a try - but odd that it doesn't work using D365 Form Editor itself

[MscrmTools]

Classic interface does not now about polymorphic lookup, give it a try with Modern designer

[epsracing77]

Will do - sorry I'm stuck in my ways!!

That seems to work, but it has other issues (MS ones!!)
