In SAP S/4HANA Cloud  Master Data, there are 2 useful apps  ‘Export Master Data’ and  ‘Mass Maintenance for Master Data’ that can be used for the Product Master and Business Partner areas to allow a customer to export master data to Excel for filtering/reporting purposes and also for mass update of data to reduce manual effort


A little-known gem of these apps is that it also allows the Export / Mass update of Classification as well!


For Classification, the initial creation is uploaded using the  Migration Object 'Object classification' in the app "Migrate your data" but afterward if you wish to mass update the classification assigned to an object such as Material ( class type 001 ) there is no Classification app like transaction CLMM for SAP S/4HANA Cloud.


The API and Interface API_PRODUCT_SRV and PRODUCTMDMBULKREPLICATEREQUEST respectively support the update of  ( POST / PATCH / PUT ) for Product Master Data fields but does not include Classification


There is an API for Classification which is  API_CLFN_PRODUCT_SRV but it only allows READ operation and not update (POST / PATCH / PUT ) as of SAP S/4HANA Cloud Essentials Edition 2102


The use of these 2 apps ‘Export Master Data’ and  ‘Mass Maintenance for Master Data’ allow update of classification as a workaround till dedicated classification apps / APIs are available in  future releases


What Apps and Roles are needed to follow this blog post to mass update material classification?

The following example was tested in an SAP S/4HANA Cloud 2102 Essentials System.
The User involved has 2 roles SAP_BR_PRODMASTER_SPECIALIST and


With the role SAP _BR_PRODUCT_CONFIG_MODELER you are able to access the 'Manage Characteristic' and 'Manage Class' apps to create the characteristics involved and to add them to a new class of type 001 ( Material Class )


With the role  SAP_BR_PRODMASTER_SPECIALIST  you are  able to follow the process of creating the products involved and then use the apps  ‘Export Master Data’ and  ‘Mass Maintenance for Master Data’ to download, change and reupload to mass change the classification


Creating the Test Data


The example consists of 2 products, 4 characteristics of different formats, and 1 class of type 001 – Material Class


Step 1: Creating the characteristics

  1. Open the app ‘Manage Characteristics’

  2. Input characteristic name, for example, COLOUR and Create button

  6. For the field ‘Number of chars’, input a value for a number of chars, for example, 8

  7. Navigate to the values tab

  8. Input a char value’s and description

Repeats steps 1 to 8 and create different characteristics of type ‘Numeric Format’,’ Time Format’ and ‘Date Format’

All characteristics have the Value assignment – select “Single-value”


Characteristic values maintained for Colour


Characteristic values maintained for Length


Characteristic values maintained for Date


Characteristic values maintained for Time


Step 2: Creating the Class

  1. Open the app ‘Manage Classes’

  2. Input class name

  3. Input class-type 001

  4. Press create button

  5. Input class description

      8.In the dropdown for each characteristic, select a value

Classify the Material

      9.SAVE when finished evaluating all characteristics


Repeat steps 1 – 9 for how many materials you wish to test with


Process for mass updating the material classification

I hope the blog post helped provide a way to mass update material classification till a decided app or tool for classification that supports all class types is made available to do it
