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?
the Web Access for ABAP is a technical feature of SAP BTP ABAP Environment, which is why it is not charged separately. This means that if you choose the free plan for the ABAP system itself, no additional costs will be created by the subscription to Web Access for ABAP.
