Helpppp!!!!!!!!!!!!!!!!!!

Question

i got an error while im loading from table 1, to table 2 by using an expression operator...
this is the error:
DEBUG INPUT ROW: 64
TABLE: "DBG$ID11_EXPRESSION_GRP1"
COLUMN: "EXPRESSION_1_OUTPUT1$1"
STATEMENT: TRACE 1998: TRACE 2003: "EXPRESSION_1_OUTPUT1$1"("DBG$ID11_EXPRESSION_GRP1_i") :=
"EXPRESSION_1_OUTPUT1"("DBG$ID11_TTCCOM010800_GRP0_i");
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
i already tried to load that 2 table without expression operator n it worked...
n i also already tried to load table X to table Y using expression operator n it worked too...
the only differences between table X n table 1 is the rowcount...
table 1 has 2402 rows n table X has 26 rows...
if i must enlarge the table for expression operator, how can i do it??
thx a lot for ur attention...
this problem almost make me mad...T_T

Answer 1

the only differences between table X n table 1 is the rowcount...
table 1 has 2402 rows n table X has 26 rows...Actually it is the data error.
while diffening output of expression that the length is correct.
check the data type and lenght of ingroup variable and check where it is assigned in outgroup.
