    Polymorphic lookup not working 9.1.3 on premise
    Hi,
    Could anyone figure it out that are Polymorphic fields actually supported on-premise 9.1 ?
    when I try it with XRM Toolbox I get the same error.
     
    Thanks in advance

    Pradeep Rai are you sure that Polymorphic fields are actually supported on-premise? I'm getting a different error when using the XRMToolbox which states "An error occured when creating Polymorphic lookup column: CreatePolymorphicLookupAttribute#2011/Organization.svc".

    Thanks.

    Hi Erik,

    Please try below link:
    https://nishantrana.me/2021/07/15/sample-code-c-for-multi-table-lookup-polymorphic-lookup-attribute-in-dataverse-dynamics-365/

    The above blog refers to dataverse but you can try same for on-premise.

    Also, Xrmtoolbox link for polymorphic lookup creator
    https://www.xrmtoolbox.com/plugins/MscrmTools.PolymorphicLookupCreator/

    Thanks,
    Pradeep.
