i have created an Enterprise BTP account and have subscribed to the 'free' plan for the ABAP environment in my sub-account. When I try to connect with the ABAP service instance from ADT Eclipse (either via Service Key or via Cloud Foundry credentials), and click on the 'Open Logon Page in Browser', I get the message that the logon was successful but I cannot login due to missing authorizations. After reading the help documentation, I realized that this is because the SAP_BR_DEVELOPER role needs to be assigned to my user and for that I need to subscribe to the "Web Access for ABAP" service, so that from my BTP sub-account, I can login to the Fiori launchpad for ABAP environment and add this role via the 'Maintain Business Roles' Fiori tile.
However, I see that there is no "free plan" for the "Web Access for ABAP" service.
Can you please confirm if I use the "Web Access for ABAP" service (default plan) with the free plan for ABAP environment, will I be charged for the use for the "Web Access for ABAP" service?
