Lack of storage space while extending an internal table

Question

Hi,
While executing a select statement my program is giving dump.
<b>ShrtText    </b>                                                                               
No storage space available for extending an internal table.                                   
<b>What happened? </b>                                                                               
You attempted to extend an internal table, but the required space was                         
    not available.   
<b>Error analysis</b>                                                                               
The internal table "IT_49" could not be enlarged further. To allow                            
    error handling, the table had to be deleted before this log was                               
    created. So, if you branch to the ABAP debugger from the display                              
    of this log, the table will there be displayed with 0 rows.                                                                               
At the moment of the termination, the following data was                                      
    determined for the respective internal table:                                                 
    Storage location: "Session memory"                                                            
    Row width: 7936                                                                               
Number of rows: 1594                                                                               
Allocated rows: 1594                                                                               
Newly requested rows: 2 (in 1 blocks)                                                                               
Please let me know how to solve this problem.
Thanks in advance

Hi Suresh ,
  The problem is with the statement where you select the data from the table
SELECT QID "Queue identification (unique key)
TRANS "Transaction counter: Batch input, statistics
BLOCK "Message counter: Batch input, statistics
SEGMT "Queue data segmentation number
MSGCOUNT "Queue data block number
VARLEN "Queue data length of user data
VARDATA
"Long String Used to Store BDC Objects in the Database
FROM APQD
INTO TABLE IT_APQD
FOR <b>ALL ENTRIES IN I_APQD</b>
WHERE QID = I_APQD-QID
AND TRANS = I_APQD-TRANS.
Please refer the how the FOR ALL ENTRIES CONCEPT works.
if still the problem exists then try using the addition PACKAGE SIZE in your select statement , what this does is insted of write all the selected data at once into the internal table it will append in packets of size specified by you.
