Hi,

I am facing some below strange error while importing a solution (for the first time) in Dynamics 365 online environment. Error message is not clear and not getting download log file option to identify the problem. But there is a 'Help me resolve this issue' link which takes to a support page: "Error code 80040203" (Invalid Argument) error occurs when attempting to import a solution into Dynamics 365 (microsoft.com), but still the error persists even after following the solution provided.

Any help to resolve this error is appreciated. Thanks

Microsoft is aware of this issue and is working on a change to remove this relationship after a delete then update.

Solution for Error code 80040203:

If you need to import the solution and can't recreate the solution package, then remove the relationship from the solution.

- Unzip the solution.
- Edit the customization.xml.
- Search for the relationship mentioned in the error: bpf_<entity>_<publisher>_<BPF Name>
- Delete all the XML for the EntityRelationship:
- Save the file.
- Zip the entire directory.
- Import the solution again.

Remove the relationship from the source and recreate your solution:

- Open the source organization.
- Select Settings / Customizations / Customize the System
- Select the Entity in the relationship:
- Expand 1:N Relationships.
- Locate the relationship:
- Select and delete the relationship.
- Publish All Customizations.
- Export the solution and import it into the target.

Hope this helps,
Regards,
Jimmywick

Try switching to classic and import your solution in the classic interface - I find that the error messages there are more helpful when my import fails. If that doesn't help, I think you'll need to provide more info on what is in your solution for anyone to be able to help you.
