Mandatory fields - Customer Master Data

Hello Experts,

We would like some of the fields in the Customer Master Data as mandatory fields, but I would like to make sure it doesn't affect any other process as for example purchasing if the Business partner also is a supplier.

The fields on the general view are
- Industry system
- Industry
- Default mail setting

The fields on the Sales area are:
- Customer group 1
- Sales office
- Sales group
- Delivery plant
- Shipping Conditions
- ABC Class
- Account assignment group

Could you please advise if you see that this would cause any issues for other processes both inside and outside sales?

Thnaks & Regards,
Vignesh SR
