Hi @Mv
As per the following document Roles and permissions in Microsoft Sentinel
If you have already assigned the Microsoft Sentinel Contributor role and the Workbook Contributor Azure Monitor role, but still can't create a workbook, you might want to check the permissions at the resource group level
Note from doc:
For best results, assign these roles to the resource group that contains the Microsoft Sentinel workspace. This way, the roles apply to all the resources that support Microsoft Sentinel, as those resources should also be placed in the same resource group.
Creating and deleting workbooks
- To create and delete a Microsoft Sentinel workbook, the user needs either the Microsoft Sentinel Contributor role or a lesser Microsoft Sentinel role**, together with the Workbook Contributor Azure Monitor role.** This role isn't necessary for using workbooks, only for creating and deleting.
Hope this helps!
