Hi,
You are trying to load data from flat then your mapping is wrong. you have to map your dimension with column numbers.
CATEGORY= *COL(1)
L_ACCOUNT= *COL(2)
L_PRODUCT=*COL(3)
Profit_Center = *COL(4)
T_TIME = *COL(5)
RptCurrency = *COL(6)
LIKE you have map each dimension with your flat file
take look at below thread for mapping
