Identity Manager Business Application Programing Interface (BAPI) is required to be installed on the SAP R/3 instance in order for Identity Manager to access the environment data and business processes. What is the procedure to rollback the BAPI transport package should the installation fail?
There is no procedure to rollback the BAPI transport package.
Please note though that starting with version 8.0, we also provide a SAP AAK 5.0 (add-on assembly kit) which you can use instead of the plain transport. You can roll back installation of the AAK if needed.
Backup the SAP R/3 system prior to the BAPI transport package installation and restore back to the original state should the installation fail.
