short dump?

hi all,

could you help on this, why it comes and how to correct?

( Termination occurred in the ABAP program "RIAUFK20" - in "SELECTION_L".
The main program was "RIAUFK20 ".

In the source code you have the termination point in line 1099
of the (Include) program "RIAUFK20".
The termination is caused because exception "CX_SY_OPEN_SQL_DB" occurred in
procedure "SELECTION_L" "(FORM)", but it was neither handled locally nor
declared
in the RAISING clause of its signature.

The procedure is in program "RIAUFK20 "; its source code begins in line
822 of the (Include program "RIAUFK20 ".)

for me it comes sometimes when no.of i/p records are more than 400 or 270. but lately it came when no.of i/p records are 79.

no clue about what it is....?

thanks &regards
