BAPI for updating CATSDB Table

Hi All,

I need to update the CATSDB table which is Timesheet Master data of Employees.

While searching for BAP in this regard, i came across BAPI_CATIMESHEETMGR_INSERT.

In this BAPI, import Parameters are Profile, testrun, release_data, agent and Text_format_imp.

I believe this BAPI doesn't serve purpose to update Employee's Timesheet.

Employee timesheet flat file will be having Employee Number as key field.

If this is the case, how to update the Table using BAPI techniques...????

Regards

Pavan
