Hi

DESCRIBE TABLE LINES lin

The current number of table rows of the internal table itab is determined and is assigned to the data object lin.The data type i is expected for the data object.

Or just use the built in function lines( ), if your working on the newest WAS.

btw, if you're just wanting to see if the table is empty, it is far better to use :

IF mytab IS INITIAL. 
or
IF mytab[] IS INITIAL.
than
lin = lines( mytab ).
IF lin EQ 0.
