PCR Report

Hi,

Question 1:

We are in a process of building a report with the following fields.

Notification Number --Workitem ID

Is there any table / function module , using which i can retrieve the Workitem ids that are relevant for a Notification Number??

and also

Question 2:

We are building a similar report with the following details.

Notification Number -- Raised By -- Approved By -- Approval Date.

and this report will be restricted based on Authorization available for the user to access the "Personnel Number" or "Position" - for which the Notification has been raised.

Is there any function module/report , which will be able to give the following details based on authorization.

Any input for the above two issues are welcome.

Regards,

Raj
