Dual write project validation issue

Posted on by Community member

I am getting the below error - I have searched for solutions but cannot ascertain the cause of the issue.

Project validation failed. [DIPV1033] Environment(True), Schema(True), and Integration Keys (False) must not be null.

It is saying that the integration keys for this dual write connection is null but I have a column that is the integration key so I am not sure why this error is persisting.

I have the same question (0)

Hi CommunityUser,

Here's what the Microsoft documentation says about integration keys (not sure if it will help)

Integration keys for the entity should match in both environments. If the entity key isn't available on either side, be sure to create entity keys. The integration key fields should be mapped to each other in the map.

Thanks,

Layan Jweihan

Go back to the list of maps, in the top menu there is a connections option, and in there there is an integrations tab. For this entity check which integration keys are set.

Hey

Keyword on the message is the last part: "integration keys (False) must not be null". So if you login to your Dynamics FnO environment, go to Dual Write and then on top select "Integration keys", you should be able to navigate to the table that threw the error. Most likely, you will have the table on the list of keys but no field selected:

Error:

And if I go to IntegrationKeys, I will see this:

To which We should generate a value:
