ERR] [16.0.9] TfsReflectedWorkItemId: Unable to match ReflectedWorkItemId(NA) as id!

[ArjGoddard]

I am getting this error that Unable to match ReflectedWorkItemId(NA) as id! while doing migration.
can you help me with the steps to resolve this issue.
please find the below error message in the screen shot.

As per our conversation, this error will occur when the data in the ReflectedWorkItemId field is invalid. Since the value its trying to load is NA I'm going to go-ahead and assume that the person that added the field to your process was trying to be helpful and added NA in the "default value" field... This is the cause of your error.

To correct this you need to:

1. Remove the Default value - Remove the Default value from the process definition. This is what it should look like:

2. Remove the invalid data from that field - Use a query to find all the work items that have "NA" in the ReflectedWorkItemId field and remove that data.

HELLO TEAM

can you help me with this.
can you help me to confirm how can i check how many work items are migrated or not in Target project.
I am sharing the log file from completed migration .

The logs you provided here show successfully migrated work items.

Validate that you are looking in the right place?

Martin, we have checked and its there , I wanted to know few thing about this using tool
can we revert the changes with this tools that work item migrated, is query with selected work item that migrated can be deleted?
and can we run this tool with specific selected work items and how we can do it, what all the configuration changes required in WIQL Query?

[MrHinsh]

Sorry, but most of what you said there is not clear or understandable! Can you split that into a list of separate questions?

It seams like you are saying that 1) you found the work items that you previously thought had not been migrated, and 2) you want to know if you can delete the work items and start over?

• You can delete them.
• Removing the ReflectedWorkItemId data is all that's necessary to be able to rerun.
• there is a 'DeleteWorkItems' processor (⚠️ it's easy to delete things you don't want to delete)

Hi Martin,

We have checked, and the work items have been successfully migrated. However, I have a few questions regarding the tool:

Reverting Changes: reason is I have fully migrated the worktems from the project and its no longer required fully migration so need to delete from the target and do the re-migration using selected workitems from source

Is it possible to revert the migration of the work items using this tool? If yes, could you provide details on how it can be done?
Selective Work Item Migration:

Can the tool be run to migrate only specific, selected work items instead of all work items?
If so, what steps or configurations are needed to achieve this?
Looking forward to your guidance on these questions.
