Perform - syntax

Question

Hi ,
    Iam trying to write an extractor for open and closed items ie form BSAD and BSID .
So i have written the logic .when i tryed to modularise the code .the function module is not acteping the perform statment
Ie when i tryed to put the logic in to a perfoem its giving a syntax error like
"Field "E_T_DATA" is unknown. It is neither in one of the specified          
tables nor defined by a "DATA" statement . . . . . . . . . .     "     
can you please provide me a solution for this .
Thanks ,
Sriram.

Hi ,
  As you have asked for below i have attached the code .
PERFORM FETCH_BSID .
*PERFORM FETCH_BSAD TABLES E_T_DATA.
this are the two perform iam trying to create just to moduralize the code .it it showing an error like .E_T_DATA is not defined which is the final extract structure .

Determine number of database records to be read per FETCH statement
from input parameter I_MAXSIZE. If there is a one to one relation
between DataSource table lines and database entries, this is trivial.
In other cases, it may be impossible and some estimated value has to
be determined.
