How to fix this error?

Procedure for System Administrators

When you upload a product to an R/3 System, you also determine what
type of component assignment will be possible:
Upload to a standard R/3 System
The product can only be used as the header product of a set product.
Upload to an R/3 Retail system
The article category you specify at the time of the upload determines
the type of component assignment: set product, display product, or
prepack product.
However, if you have uploaded the product to various R/3 Systems in an
inconsistent manner, this will mean that you cannot assign components
consistently either.
