Optional/Required field change via Migration Object Modeler in Public Cloud?

[naresha589272]

Hello SAP Folks,

We are facing issue while Migrating Material without Material group in Public cloud, we got the error shown below.

Even though the Product/Material Group is not mandatory in Standard Migration template still we are facing issue.

Need your help to go forward.

Thanks

Hello Naresha,

that message ID MM 85 is thrown by the API used to migrate the data. That error message has nothing to do with the visibility definition of the migration template. Within the migration template you will only see fields being marked as mandatory that are always mandatory- Fields that can be maintained mandatory or not mandatory via business process configuration or fields that are dependent on field value combinations mandatory or not mandatory are never marked as mandatory within the migration template. Each sheet/structure of the migration template has an assigned database table. Setting a field Mandatory or not is done via database constraints. Changing database constraints dynamically is not possible. 

For the API the material group is a mandatory field. You must either verify if you can configure this field within the different business process settings for material master to be not mandatory or you must provide a value for that field. 
You can also check the KBA 2756835 - Material Group MARA-MATKL is mandatory for MM02 despite set as optional - SAP for Me
There it is explained that if data for purchasing view is being used, material group is always mandatory.
