Can we update the effectivity_date of BOM_components_b to before date by datafix
                    
 Hi experts 
                In 12.1.3
                 When initial BOM data, the effectivity_date of components are incorrect. Now we want to update the effectivity_date of BOM_components_b to before date by datafix. 
Is there any impact of this datafix? We cannot update this date to before by API. 
In our instance, we use common BOM.
Thanks in advance
