9.9 Do I have to activate business functions in a specific client of the SAP system?
In principle, the activation of a business function is client-independent, i.e. the new functionality will be available in all clients of the SAP system.
However, the activation of a business function via transaction SFW5 will also trigger the extraction of template customizing for the new business function. The template customizing will be extracted into a specific client of the SAP system. In order to avoid overwriting existing customizing, you should activate business function in client 000 and follow the instructions of SAP Note 337623 carefully.
My Basis team members are hesitant to activate BFs in client 000 b/c they consider this golden and "should not be touched". They want to activate this in client 100 b/c it's client independent anyway, but I wanted to better understand the potential impacts of not activating in 000. What customizing could be overwritten by not utilizing client 000? How could this negatively impact the any config/customizing, etc that is already in place in the system?
Any input would be appreciated!
