Maintain authorization between multiple subaccounts in SAP BTP

Hello everyone,

Error was: No ABAP environments in CF space found when creating list report object page in SAP Business Application Studio.

This is due to ABAP enviornment present in another subaccount but I want to achieve this by giving authorization between these 2 subaccounts.

May I know, how do I connect with another subaccount? What are the steps to give the authorization to get ABAP environment from another subaccount? I'm the one global account user managing both subaccounts.

Is there any option? How do subaccounts play role in SAP BTP?
