BizTalk 2009 Change to AX Interface…

Background:

Me: I am very new to BizTalk; however, I have worked with it for about 6 months now and prior to that I did some Tibco development.

Project: We are replacing a legacy FileMaker Sales Order application with MS CRM 4.0.  The current system has been using BizTalk to put sales orders into out AX system. 

Problem: 

Recently, I was asked to make a minor change to the orchestration.  This entailed removing a current field-to-field mapping; routing the field to a “new” field in AX and converting it to a #0.00 format on the way.  The “new” field was not available in the Production Interface, so some changes were made to the interface which exposed the new field.  Since that change was made, I have been getting the following error:

3247785-4438347 Error Description :Microsoft.XLANGs.Core.XTransformationFailureException: Error encountered while executing the transform Integration.Crm.AX.Maps.Map_ProdTicket_To_UnitInkDieMaterialString.

Because of the very minor effort required to perform the change, I can’t believe that the inkitemid1() is now suddenly failing.  I have tried changing the map back to the original, but no change in the error.  To my pea brain, this is saying that there is something wrong with the new AX Interface.  (I replaced the original by creating a dummy program and Add(ing) a new generated item.  When I compare the original and new, they appear to have the changes I expect (i.e. – the new field shows up in the XML).  Have I failed to register the new interface through some arcane method only known by real BizTalk Gurus?  Or, am I barking up the wrong tree?

Any help with this stinker will be greatly appreciated…
