SAP BPC script logic ignoring account type

Hi Experts.

I have written a default script logic. I am loading data from flat file and executing script logic for the load. this script logic should consider account type and then create record in database. But it is not behaving that way.

flat file record:

account     time           category        amount

A100          2015.01   ACTUAL        100

dimension : Account

account       acct_type

A100          EXP

A200          INC

script logic:

*when account

*is A100

*rec(factor  = 1, account  = A200)

*endwhen

this script is generating record 100 instead of -100 in database.  but script works correctly for input template.

Please help.

regards,
