Read Error Messages and data from Transaction /AIF/ERR

Hi All,

We have a requirement to build a custom report to display error messages and other data from Transaction /AIF/ERR, Can someone please let us know how to read the data from this transaction.

Found in some other threads that we can read using below method /AIF/IF_APPLICATION_ENGINE~SELECT_IDX_TAB_ENTRIES /AIF/IF_APPLICATION_ENGINE~READ_MSG_FROM_PERSISTENCY.

But not able to call these methods, Please provide some sample logic using above methods or please let us know if there is another way of fetching data from /AIF/ERR

Thank you.
