Requisitioning BU unavailable in Classic My Receipts (User using RSSP)

Summary:

Hi All,

We have assigned a custom role and assigned appropriate data access to user so they can create requisitions from Responsive SSP.

However, when they try to do receiving in Classic 'My Receipts', the requisitioning BU is not available.

Since we have already given the data access to new role, Is there any other role required with data access to do self receiving in Classic My Receipts?
Also, as I understand, by 25C release, while Classic SSP is retiring, Classic Manage Receipts will still be there. Can you confirm on this?

Note: A custom role is provided to user with below privileges
