A managed solution cannot overwrite the AttributeMap component ....

Posted on by l ringel

Hi there,

I am trying to import an update to my current solution and am receiving this error.

"A managed solution cannot overwrite the AttributeMap component with Id=f3aa3ba7-997b-e711-810c-e0071b6a10b1 which has an unmanaged base instance.  The most likely scenario for this error is that an unmanaged solution has installed a new unmanaged AttributeMap component on the target system, and now a managed solution from the same publisher is trying to install that same AttributeMap component as managed.  This will cause an invalid layering of solutions on the target system and is not allowed."

The error log shows that lead-contact is causing this error. I have recently made a few mapping changes within our live site. so i went back and removed those changes to see if that would make the difference but it didn't.

can anyone help me with this.

Thank You!

Leibish Ringel

    We had this problem now when upgrading the Field Service solution from Version 7.5 to 8.7. MS Support provided us a nice step by step instruction for what to do:

    Hey guys.. just got this one solved

    I was facing issue with both Contact-Lead and Incident-IncidentResolution in a clean Trial Environment

    I navigated to the destination environment, opened the Relationship, opened the Mappings and DELETED the mapping that was causing the issue

    Re-imported the solution and all went good

    Remove the EntityMap tag from Customization xml

     Extract the solution .zip file, open customization.xml and search with <EntitySource>lead</EntitySource> and then choose your source and target are the same entity name.

    Now replace the tag with <AttributeMaps /> and then create a solution's zip and import it again.

    <EntityMap>

    <EntitySource>lead</EntitySource>

    <EntityTarget>contact</EntityTarget>

    <AttributeMaps>

    …

    </AttributeMaps>

    </EntityMap>

    Can you look at the 1-N and N-N relationships between lead and contact?

    If you can find, either in log file or figure out which relationship is the one that is causing this issue (on production), remove it and try to reimport.

    I did some searching and most solutions are for On-Prem, not Online.

    Hi,

    Is this On-Prem or Online?

    If On-Prem, you can check which mapping is causing this issue by going into SQL and executing the following command:

    select SourceEntityName, SourceAttributeName, TargetEntityName, TargetAttributeName from AttributeMap am

    left outer join entitymap em on em.entitymapid = am.EntityMapId

    where am.AttributeMapId='f3aa3ba7-997b-e711-810c-e0071b6a10b1'

    Once you get the component, remove it from the target system and try re-importing it.

    Hope this helps.
