Tax Registration REST API error on existing Validation Type

Summary:

When we try to create new tax registrations at party level, including the Validation Type ORA_BE_VAT, with the REST API, we sometimes get an error message:

"You must provide a valid value for the ValidationType attribute. (ZX-885076)"

When we create them through the UI or using the FBDI, using the same Validation Type ORA_BE_VAT, we don't get any errors.

Based on extensive testing we noticed that it only fails when the party is a supplier. For those that are only a customer it works fine.

Has anyone else experienced this issue?

I guess I better raise an SR but I wanted to check first if anyone has had the same issue.
