Problem with fetch cursor statement

Question

Hi,
I am using FETCH CURSOR statement to fetch the data from a database table with package size. For the fetched records I am doing parallel processing using parallel processing frame work in banking system.
Here the problem is for the first iteration it works fine but when it comes to FETCH NEXT CURSOR in the second iteration , programs gets dumping by saying that 'CURSOR already closed'.
I am not closing the cursor in the program but some how it got closed some where in the standard function module which I used for parallel processing.
I used WITHHOLD also along with FETCH CURSOR but no use. Please let me know how to avoid the cursor to get close.
Below is my code
IF NOT l_tab_product IS INITIAL.
    OPEN CURSOR WITH HOLD lv_cursor FOR
     SELECT contract_int prodint cn_currency mig_grp
          INTO TABLE gt_cont
            FROM bca_contract
            FOR ALL ENTRIES IN l_tab_product
            WHERE prodint = l_tab_product-prodint
            AND   mig_grp IN s_migrp.
    DO.
      FETCH NEXT CURSOR lv_cursor
                        INTO TABLE gt_cont
                             PACKAGE SIZE lv_size.
      IF sy-subrc <> 0.
        CLOSE CURSOR lv_cursor.
        EXIT.
      ELSE.
parallel processing logic
ENDDO.
ENDIF.

Answer 1

Using Withhold will not make sure that the cursor will not get closed because of commits.
SAP Doc says
If the addition WITH HOLD is specified, the database cursor is not closed by a database commit executed using Native SQL. The addition does not have an influence, however, on implicit database commits or on any rollbacks which always close the database cursor.
You have to check the part written in your parallel processing logic.
As Brad said please donot dump your old threads like this.
