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.

Step 3

Select Bom for which user wants to do the changes & click on Edit/Lock Button

Step 4

After that Field will became Editable user have to change the fields & save

Now BILL OF MATERIAL has changed as per requirement massly.

Thanks & Reagrds
