How to fix this error?

Please verify whether you are editing a Terminalling related document.
With Terminalling, the following rules apply for sub/base product
relationships:
Non-BOM (bill of materials) item
Base product and sub product have to be the same.
BOM item (base product assignment only supported at header level)
a.) If there are multiple components, then the base product must equal
the header product.
b.) If there is only a single component, then the base product must
equal the component product.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
