How to count the number of rows in the table?

Hi all

Need your help again.

In SAP Workflow I want to count the number on rows in the table. The table conststs of records of infotype 1000 (structure: p1000, field: OBJID), it's filled in workflow. Is there any way to find out the number of rows using standart existing methods or functional modules? Programming would be quite difficult.

Regards,

Maria.
