HR_ECM_READ_GLOBAL_COMP_DATA . URGENT!!!!!!!!!!!

Hi All,

I am new to HR ABAP. I have to display the Performance Rating of an employee for which i am using FM HR_ECM_UI_DISP_APPRAISAL in a Smartform.Parameters and a populated table Key_objects are passed.

But inside above FM there is an another FM HR_ECM_READ_GLOBAL_COMP_DATA which returns some populated tables.I guess it contains some Dynamic Columns.

Please can any one suggest how the tables returned by FM HR_ECM_READ_GLOBAL_COMP_DATA are getting populated?

Right now FM HR_ECM_READ_GLOBAL_COMP_DATA is returning empty tables in my code.

My Smartform is not triggered by any Portal but through a Transaction code.

Thanks.
