SAP come back suggesting favorites option available only with additional add-on GBX01HR5.
Our system was having the add-on GBX01HR only. We went installing add-on GBX01HR5 and post installation we were facing error "RFC Error: Function module: "HCM_CATS_GET_DEFAULT_DEP" not found" coming in the My Timesheet Fiori App which was blocking us from running the app.
We went back to SAP reporting the issue and SAP suggested us to implement the below mentioned SAP Notes in the same order and provided a reference thread http://scn.sap.com/thread/3821029 for avoiding any issues while implementing the notes:
1) Apply note 2221429
2) Apply note 2223506.
3) Apply note 2223505
After implementing the above mentioned 3 notes error got resolved and favorites option is enabled.
With the standard profile parameters, favorites is working fine but when we tried testing with the user having custom profile assigned which is having additional input parameters, we are facing error "RFC Error: Exception condition "NOT FOUND" triggered".
We've reported this issue with SAP and currently SAP is working on the solution.
I will get back to the thread with more information once SAP provides us the solution/update to the reported issue.
