Reg: SAPSQL_STMNT_TOO_LARGE

Question

Hello All,
     While running a customized report I am getting the error 'SAPSQL_STMNT_TOO_LARGE' and the report is throwing a dump. The dump shows the line of code or the query which is failing. The query is as follows:
SELECT bvbeln bposnr bmatnr bwerks
         avkorg aerdat
         bzzhrtosec bzzhrtitsi
        APPENDING TABLE t_so
   FROM  vbak AS a
         INNER JOIN vbap AS b
         ON avbeln = bvbeln
     WHERE  a~vbeln  IN r_vbeln
     AND    b~abgru = space
     AND    b~pstyv  IN s_pstyv.
I analyzed this query and I found that the internal table t_so already has 72,000 records before this query has got executed. Also this query is trying to append some more records on to the internal table. So I felt that this might be because of larger volume of data. But I am not sure that whether this is the exact problem. I am also not sure for what reason this error comes. If anyone is aware of this thing, kindly let me know what are all the possibilities for this error to occur so that any one of them might fit to my problem.

Either of your SO_PROJ, SO_PSP, SO_PRART or SO_PBUKR are containing a lot of records. If you do a SQL Trace (ST05) on your query you will be able to figure out how the database parser is opening up those SELECT-OPTIONS tables.
The work around for this kind of dump is to limit the number of records that you pass to a SELECT query using a SELECT-OPTIONS table. I am attaching a pseudo code for your perusal.
I have assumed that your SO_PRART has a lot of records. And for the MAX_RECS variable, you will have to play around a bit (eg. set it as 1000, 2000, 3000) till you stop getting a Short Dump.
Also you have to use APPENDING, in place of INTO TABLE, else it will overwrite the table inside the WHILE-ENDWHILE loop.
*Now break the select options into n parts each containing
*MAX_RECS no of records
WHILE NOT so_prart[] IS INITIAL.
  REFRESH r_aufnr.
*This loop will break so_prart INTO a SELECT-OPTIONS table that will
*contain MAX_RECS no of records.
  DO max_recs TIMES.
    READ TABLE so_prart INDEX 1.
    IF sy-subrc EQ 0.
      MOVE so_prart TO r_aufnr.
      APPEND r_aufnr.
      DELETE so_prart INDEX 1.
    ELSE.
      EXIT.
    ENDIF.
  ENDDO.
  SELECT prps~pspnr  proj~pspid  prps~posid  prps~post1
         prps~objnr  prps~psphi
     APPENDING TABLE g_t_psp
     FROM prps
     INNER JOIN proj  ON prps~psphi = proj~pspnr
     WHERE proj~pspid IN so_proj
       AND proj~loevm EQ space
       AND prps~posid IN so_psp
       AND prps~prart IN r_prart
       AND prps~loevm EQ space
       AND prps~pbukr IN so_pbukr.
ENDWHILE.
