Manually populating appraisal values in IT7408/7409

Hello Friends,

We are on SAP ECC 6.0 EhP6.

The employee appraisal processes are handled outside SAP and the appraisal ratings are provided. Our business requirement is to manually upload these ratings to Talent Management infotypes (7406, 7408, 7409).

I understand that Talent Management infotypes are populated after Talent Review Meeting (TRM) is completed.

Since we are not conducting TRMs, I would like to know if there is an alternate way by which we can manually populate the infotypes with values.

I am thinking of using custom coding to achieve this functionality. Can you please let me know if this a feasible option.

Any inputs/suggestions would be greatly appreciated.

Regards,

Arun.
