Runtime Error # DBIF_RSQL_INVALID_RSQL for large size BOMs

Question

Hi All,
I am facing problem running a custom report for Routing summary. When Executing the report gives the above runtime error.
ShrtText: Error in RSQL module of database interface. 
Error analysis :
An exception occurred. This exception is dealt with in more detail below                      
    . The exception, which is assigned to the class 'CX_SY_OPEN_SQL_DB', was neither caught nor passed along using a RAISING clause, in the procedure                              
     "CP_SC_MTK_LOAD_COMPLEX_BY_TSK" "(FUNCTION)"                                                 
Since the caller of the procedure could not have expected this to occur, the running program was terminated.                                                
    The reason for the exception is: The SQL statement generated from the SAP Open SQL Statement violates restriction imposed by the database system used in R/3.                                                                               
Possible errors:                                                                               
o The maximum size of an SQL statement has been exceeded.                                    
     o The statement contains too many input variables.                                           
     o The space needed for the input data exceeds the available memory.
How to correct the error                                                                               
The SAP Open SQL statement must be divided into several smaller units.                        
    If the problem occurred due to the use of an excessively large in an IN itab construct, you can use the addition FOR ALL ENTRIES                             
    instead.  When you use this addition, the statement is split into smaller according to the restrictions of the database system used.                                                                               
You may able to find an interim solution to the problem in the SAP note system. If you have access to the note system yourself,                       
    use the following search criteria:                                                                               
"DBIF_RSQL_INVALID_RSQL" CX_SY_OPEN_SQL_DBC                                                   
    "SAPLCPSC" or "LCPSCU03"                                                                      
    "CP_SC_MTK_LOAD_COMPLEX_BY_TSK"   
This report uses SAP standard Function module "CP_SC_MTK_LOAD_COMPLEX_BY_TSK" in the select statement.
When Analysed, We found that since the BOM size for routing is large(More than 2000 components), this dump is coming. for rest of the routings, the report works fine.
I could not found any SAP note relevant for this.
This is definitely related to large BOM size, if anybody of you came across such problem and how to correct it now.

Hi,
We did solve this problem. This problem usually comes when there is very large records in internal table (More than 2000 Approx).
We need to split that select statement and make multiple statements so that the memory overflow doesn't happen. refer SAP note: 13607.
We modified the coding as follows by splitting the SELECT statementu2026
SELECT DISTINCT MANDT PLNTY PLNNR PLNAL MATNR WERKS VBELN POSNR
        INTO CORRESPONDING FIELDS OF TABLE E_MTK_IDENT
        FROM MAPL FOR ALL ENTRIES IN I_TSK_IDENT
        WHERE PLNTY =  I_TSK_IDENT-PLNTY    AND
              PLNNR =  I_TSK_IDENT-PLNNR    AND
              PLNAL =  I_TSK_IDENT-PLNAL    AND
              MATNR IN I_CPSC_MTK_SEL-MATNR AND
              WERKS IN I_CPSC_MTK_SEL-WERKS AND
              VBELN IN I_CPSC_MTK_SEL-VBELN AND
              POSNR IN I_CPSC_MTK_SEL-POSNR AND
             (FREE_WHERE-WHERE_TAB).
  SELECT MANDT PLNTY PLNNR PLNAL MATNR WERKS VBELN POSNR
         INTO CORRESPONDING FIELDS OF TABLE E_MTK_IDENT
         FROM MAPL FOR ALL ENTRIES IN I_TSK_IDENT
         WHERE PLNTY =  I_TSK_IDENT-PLNTY    AND
               PLNNR =  I_TSK_IDENT-PLNNR    AND
               PLNAL =  I_TSK_IDENT-PLNAL    AND
              (FREE_WHERE-WHERE_TAB).
  Delete E_MTK_IDENT where matnr NOT in I_CPSC_MTK_SEL-MATNR.
  Delete E_MTK_IDENT where werks NOT in I_CPSC_MTK_SEL-WERKS.
  Delete E_MTK_IDENT where VBELN NOT in I_CPSC_MTK_SEL-VBELN.
  Delete E_MTK_IDENT where POSNR NOT in I_CPSC_MTK_SEL-POSNR.
Hope this helps you.
