SAP MDG Create New Entity (used storage/use type 1)

Hi Experts,

I'm facing a problem to create a new entity type.

I have set "used storage/use type 1" but the system did not generate all necessary database tables except for check table.

What would you suggest I do??

Sincerely,

>You use storage/use type to specify whether and how master data can be changed in Master Data Governance. The storage and use type also indicates which database tables are generated by the system:

1 - Changeable via Change Request; Generated Database Tables

The master data of this storage and use type can be changed in Master Data Governance with a change request. The system generates all necessary database tables: check and text tables as well as additional tables, for example, for attachments and sets.
