How To Fix LTR2_BASIS_CHECK574 - No external links to other business objects are allowed for data model &1

SAP Error Message - Details

• Message type: E = Error

• Message class: LTR2_BASIS_CHECK - LTR2 Messages of Checks in Check Framework

• Message number: 574

• Message text: No external links to other business objects are allowed for data model &1

What causes this issue?

The current data model is a child of another data model in the same
business object. The dependency between the two data models is defined
by an internal link. In this case, it is not allowed for the child data
model to have another parent-child relationship with a parent data model
in another business object (external link).

How to fix this error?

Please follow these steps to circumvent the modelling restriction:
Create a new business object.
Recreate the child data model from the current business object in the
new business object. Keep in mind that all links that were previously
internal must now be external.
Add the required external links to the data model in the new business
object.
If you have added the original business object to an embedded
specification, then please deactivate the current data model.
