What the tcodes to archieve/delete a material BOM?

Look at this option to delete a material BOM
 
There are two ways of deleting BOMs: 
- Using the Delete function. 
- Using the Deletion indicator. 

If you select the deletion indicator, the BOM is archived in the next reorganization run, and can be deleted if required. In the BOM header, you set the indicator that controls physical deletion after the archiving run. You can still process the BOM within its validity period.This also applies if the deletion indicator is entered with reference to a change number with a valid-from date that is after the date of the next reorganization run 

You can use the below mentioned tcodes:
CS25/CS28        Archiving for BOMs
CS26                  BOM deletion
CS27                  Retrieval of BOMs
