Problem to change Bom?

Question

Hi,
Beacuse raw material be replaced, I need change the BOM.
When I use T-code cs02 to operate, I find that "valid from" and "valid to" is disabled, I can't change it.
If I directly change the material in the BOM, the changed of  BOM is activated at once, but I hope the BOM become effective on the specific date.
Please give me the guide?
Thanks & best regards

HI
what you mentione dis write, it takes immediate effect,
if you want the validity you need to use Change mangement.
Engineering Change Management is a central logistics function that can be used to change various aspects of production basic data (for example, BOMs, task lists, materials, and documents ) with history (with date effectivity) or depending on specific conditions (with parameter effectivity).
A change with history has the following distinctive characteristics:
It takes effect under precisely defined conditions (precise date or specific effectivity parameter value).
The changed object is saved twice: in its state before and after the changes.
A change master record or ECR/ECO controls and documents the changes.
Choose Logistics --> Central functions -->Engineering change management --> Change master -->Create.
The Create Change Master: Initial Screen appears.
Enter an change number.
Do not enter anything if you want the system to assign a number itself
Select the type:
Change master
Select the change master record's function:
Without release key
enter-> write descriptin, valid date , change number status,then you get the object types select tick for active and object for you required data(ex BOm or routing) and click onobject F7, and enter the BOM materi code and save.
