HI Experts,

I am using BTS 2013 version, I have X12 parties configured in my environment and i use to send X12 messages to external partners from my application.

So for that i configured Send ports in parties.Every thing is working fine.

But when i try to delete my BTS application, am getting below exception.

Delete of ApplicationNode failed.

Error while removing application "EDIApp". (mscorlib)

Change requests failed for some resources. (Microsoft.BizTalk.ApplicationDeployment.Engine)

Unable to process delete change request for BizTalk binding "". Import bindings (unbind) failed. (Microsoft.BizTalk.ResourceManagers)

Column 'nvcName' does not belong to table bts_party_sendport. (Microsoft.BizTalk.ExplorerOM)

When i remove the send ports from party and then try to delete it's letting me.

Could any one have any ideas?

That is as expected Sandy. 

You cannot delete an application if it contains a send port that is referenced by a party. You can delete the reference from the party, delete the send port, or move the send port to a different application. For instructions on performing these tasks, see How to View or Edit a Party, How to Delete a Send Port, or How to Move an Artifact to a Different Application.
