Override Validity with Change Numbers
Use
You use this function if you want to set the change statuses, generated by the system with reference to change master records, as valid or invalid, regardless of the parameter variant. This may be worthwhile in the following situations:
You override the validity when simulating if, for example, you want to check the components that would be in a BOM, if a particular change number were valid or invalid.

For example, you have newly designed an assembly. As you do not want to use the assembly in your product until a test phase has been completed, you want the change to take effect in the future. You therefore make the change with reference to a change number with date validity, whose valid-from date is in the future.
You create a sales order for one of your charter clients, who wants to test the product with the new assembly. So you want to assemble a change status now, that will become valid in the future. When you enter a parameter variant in the sales order, you validate the change number you used to create the new assembly.
Features
When you validate a change number, the system also sees all change statuses generated with reference to this change number, as valid. This applies
