• Are you allowed to change this field with VA02 (what is line item status, are there followng documents, etc.)
• In recent versions there is a MATERIAL_LONG field for long material number
• Search and read also OSS notes such as 3260628 - BAPI_SALESORDER_CHANGE does not set MATNR_CHANGED

So , if i make MATNR Field editable in va02 through user exit enhancement , will i be able to change through bapi a well ? Please reply

The first question to resolve before making a mess of the database is why this field is protected.

Also you should post relevant part of your code, how did you fill the BAPI parameers.

[Yogeshwaran]

The field MATNR is protected in standard only , also i have filled all bapi parameters correctly according to bapi_salesorder_change example , like updateflag etc...

So SAP prevents you to change this value, so don't change it?

(Ask functionnal on actual requirempent, you could cancel current item and create a new item in the order)

Well that's the custom development that clients wants it 😥

Hi Instead of changing the MATNR in VA02 which you can not do as STANDARD practice.

Delete the line item and add the new material in new line item.
