Hi,
This document explains how we can do the mass update for a BOM.I feel that this is a basic question asked in the forum for many times .
Massly we can update a Existing BOM by CS20 OR CEWB Transaction
1. Tcode CS20
First select relevant option 1) user wants change item data
2) Delete material
3) Add Material
4) Add Document
5) Add class

After that you can update following field Quantity
costing relevancy indicator
Bulk material
Item Text
But it is difficult to remove costing relevancy indicator through CS20 if it is defined as blank in the system .
For that process we will use another Tcode CEWB
Step 1
Give current working area as SAP_ITEM

Step 2
Go to item tab in the component field give the component code ( for which user wants to do the changes in all Bom)
click on Load BOMS & Tasklists Data.
