Posted on by Community Member

Good morning to my Dynamics Community people,

I have set up workflows on the Purchase Order and Vendor Invoicing processes.

However, I have received this error "Error in call of method EventContextInformation.unpack" on the Vendor Invoice workflow after it was the form was submitted. Although I tried recalling the workflow, it was to no avail. The error simply reoccurred.

Is there anything else I can do to get the pending invoice out of the workflow?

Regards

The error message represents the state that Record is missing against which workflow process was supposed to generate notification.

There is a Hotfix provided by Microsoft for this issue. Not sure, if that can work for you or not. For my case, the hotfix did not helped.

This week I will be working on my case. Once I finish further debugging, I will post my findings. Meanwhile you can have a look at reasons of this issue and debugged stack track.

Thanks for the feedback.

What "Record" could it be referring to? The process is PO > Receipt > Invoice. I can't see what would be missing.

Secondly, what do you mean by debug stack track? I'm not familiar with coding, if that's what you mean.

Also, is there any way to retrieve the document if I were to deactivate the workflow?

1) What "Record" could it be referring to?

it is referring to same record which is origin. Speaking in functional language, when any activity happens in workflow, a notification is generated. e.g. on Approval a notification can be sent to a user ABC, or to workflow originator.

The system fails to find the record, for which it needs to send notification, i.e. same document for which workflow is being operated. The major reason of failure can be inconsistency in primary key(unique identification of a document)

So, it is referring to same record i.e. on which workflow is being operated.

2) Secondly, what do you mean by debug stack track? I'm not familiar with coding, if that's what you mean.

Yes Stack and FIFO are Data Structure terms. In functional Language Stack Trace simply mean "a lead starting from your point of failure to your work start point"

I am afraid that it may not be very easy for you to fix if you are not aware of coding. As debugging is required in such cases.

3) Also, is there any way to retrieve the document if I were to deactivate the workflow?

Yes, you can deactivate workflow, and you can continue without workflow provided that your organization can afford that. For existing/pending documents you can update status by Code to "Approved"

I appreciate your assistance. I suppose I'd have to pass this issue unto a developer who may be more familiar.

Best regards.

Yes, that would be a much better, as on site development consultant can look deep.

Do provide us feedback, once you get any update

Hi,

I have changed title of question from "Workflow that won't work..." to currently what you can see.

Keeping meaningful titles can help new comers to search quickly.

I got same error while recalling the Vendor invoice workflow. And i have tried many times to recall it but workflow got stopped again.

Finally i have checked in vendInvoiceInfotable and found 2 records one with status executed and one with waiting. So i have checked the "Invoice History and matching details" and deleted the record which having status waiting. and the issue resolved.

Thanks,

Jay
