Can anyone also guide me on how to perform changes in standard UI code for getting "Existing Sign Up" page functionality working in ISU server scenario only and so changes need to done to call ERP_UTILITIES_UMC_URM service rather then calling CRM_UTILITIES_UMC_URM service in UMCUI5_MOBILE (private/logon) code.I need to do check for getting the functionality works 'User sends a user creation request based on contract account/business agreement ID and email (existing customer scenario)' in umcui5_mobile app in ISU.
