Problem in generating Dymanic internal table

Hi,

I am working on one requirement where my program has to generate Dynamic internal tables, So I am creating dynamic field catalog and passing it to the class

CALL METHOD CL_ALV_TABLE_CREATE=>CREATE_DYNAMIC_TABLE

           EXPORTING

             IT_FIELDCATALOG           = GT_DYN_FCAT1

           IMPORTING

             EP_TABLE                  = GT_DYN_TABLE1

           EXCEPTIONS

             GENERATE_SUBPOOL_DIR_FULL = 1

             OTHERS                    = 2.

         IF SY-SUBRC EQ 0.

         ENDIF.

The above code is written in loop and the no. of loops will vary, it is working fine for around fifteen loops and after that it is not generating the Dynamic internal table and giving the SY-SUBRC = 1. It means the exception GENERATE_SUBPOOL_DIR_FULL. I came to know that during runtime max 36 dynamic subroutine pools will be generated after that it will not create Dynamic internal tables.

Please let me know if anybody faced same issue and any alternative to resolve this issue. my SAP version is 6.0.

Dileep.
