Error Saving Record - TargetAttributeValidationPlugin - CRM 2011

Question

Hello,
I'm having a problem when I save a new record for the quotedetail and this record is opened via "Xrm.Utility.openEntityForm("quotedetail", null, parameters);".
When it opens shows the entity with the parameters loaded correctly, but when I try to save it, it gives this erros:
Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: An unexpected error occurred.Detail:

</TraceText>
</OrganizationServiceFault>
This error doesn't occur if I'm saving the record opened normally and inserted the information.
I've validated all the parameters passed (if the field exists and if are well written).
I've done some tracing on the server and the error I got was this:
The Web Service plug-in failed in OrganizationId: ccfb7519-dedf-4f88-8a1f-32da85d2e277; SdkMessageProcessingStepId: c754fdb4-ef2f-4f2c-b49f-186214ab4dcd; EntityName: quotedetail; Stage: 5; MessageName: Create; AssemblyName: Microsoft.Crm.ObjectModel.TargetAttributeValidationPlugin,

I have plugins that run on Pre-Operation (1) and Post-Operation (2) Sync of the entity, and I have Contains validations for the key's I'm trying to access, although the error that gives when I try to save it is related to this: Microsoft.Crm.ObjectModel.TargetAttributeValidationPlugin
- that must be an internal plugin
On the PluginRegistrationTool can't find this SdkMessageProcessingStepId: c754fdb4-ef2f-4f2c-b49f-186214ab4dcd.
Can anyone help on this?
Cheers,

Hello,
Came across that very same issue today only with Opportunity Products. In my case specifically a required field was not being passed in the request and the error kept coming up.
On this entities it's common that internal plugins use certain fields for different operations so my best guess is you're probably missing one or two parameters in your message request.
You're correct that it is an internal plugin and you won't be able to find it via Plugin Registration tool. It's responsible to validate wether all the required fields are passed for the system entities.
