ABAP Program Short Dump in BW

Question

I have created a dynamic program which would read any table name as input parameter and print the contents. Its working if I use  a small table(3 fields) and the same program is throwing short dump if pass a big table.
Shortdump
"SAPSQL_SELECT_TAB_TOO_SMALL" C           
"ZBW_DYNAMIC_ITAB1" or "ZBW_DYNAMIC_ITAB1"
"START-OF-SELECTION"                      
Error in the line below

>>>>> select * into table <dyn_table>

Hi,
The dynamic table that is generated is not converting the exact output length in case of packed numbers.
Foe eg : If there is an packed field of length 7 , the dynamic table is converting it to Char 7 , but the actual output length of Pack 7 is 15.Hence it is giving short dump saying that Internal Table length is not sufficient.
Probably it might have worked for smaller tables for you because you might not have used Packed field in there.
