3697251 - Error: "Extension field XXX already exists with different data type: ABC" during field creation in Account Service

1. Navigate to settings.
2. Access Extensibility Administration.
3. Select the Account Service.
4. Attempt to create a new field with Label and technical name XXX; Data Type: String; Format: UUID.
5. Observe the error message: "Extension field XXX already exists with different data type: ABC"

• The error "Extension field XXX already exists with different data type: ABC" is raised because a field with the name XXX already exists in Individual Customer Service with a defined Data type ABC and Data Format DEF which is not String Data Type as chosen (DEF is the Data Format of the field XXX in the Individual Customer Service).
• For creating a field under Account service with the same name XXX, the Data Type, Data Format, and Field Length must all match across services: Account, Competitor, ContactPerson, Employee, IndividualCustomer, Partner, PartnerContact, Supplier, SupplierContact. 

1. This is the system expected behavior.
2. Create the field XXX with same Data Type as ABC, Data Format as DEF and Field length (if applicable) as in Individual Customer service and the field will be created without errors.
