How to remove old Class in Material master?

[Former Member]

Hello SAP gurus,

A class has been assigned to one material and now my requirement is assign a new class to the material. Now the issue is after assign the new class while using the material in an order all the characteristic (from old and new class) is populating.

So is it possible to remove the old Class from that material?

Thanks

Thanks for your quick reply.

I want to delete the Class from the Material master.

If you are referring to material class then you should be able to delete the class assignment from MM02. However, if it is a batch class then it is a tough process since the batches created with respect to the material have to be deleted and archived before attempting to remove the batch class assignment.

Thanks for your help.

Yes it is batch related class. So can you please tell me the process how to proceed.

Identify the batches that are created for this material.

Delete the 'class' from each of the batch master.

Once the above assignment has been disabled for all batches pertaining to that material then you can go back to MM02 to delete the batch class.

Thanks for your reply-Now just need one clarification.

Below is my scenario u2013

A class is assigned to one Material now we donu2019t want that class so in CL02 we changed the validity period. Then with a new validity we assigned a new class to the material, still the old class is there in material master. While creating an order on document by using that material all the characteristics (from new and old class) is coming but we want only the characteristics from the new class.

After changing the validity period why the characteristics are coming in the sales order.

need your help.

Thanks for your support.

While deleting the class in MM02 screen system is throwing error message- "Configured objects: the assignment cannot be deleted". So can you please help me on this how to delete the class from that material.

The validity period allows whether an object assignment can be further made. As for the error, have you verified that all batches have been un-classfied? In the batch master, in the classification tab, you should not see any characteristics if you have done this. If you are receiving the error despite un-classfiying the batches then can you double click the error and check the details of the error?

Hello Kalyan

I raised an OSS note for this and below is the reply from SAP. Thanks for your support.

Thank you for your query.

To delete the old class their are 2 options available to you .

1 )

To delete the old class you have to remove the assignments of where

it is used . Please access the old class in CL03 and then the menu

path "Environment - Where used list"

Once all assignments are removed you should be able to delete the class

2)

You could use a change number created in transaction CC01 to delete

the class from the classification view.

Please review note 166530 which explains about the deletion of

classification data.

Please refer to the online documentation at help.sap.com and the

Classification section where it states :

Once you have used engineering change management to process

characteristics, characteristics of a class, or classifications, you

must use engineering change management for all further changes.

I hope the information is of help , please test carefully on a Non

Productive system first
