How to load data for accounts that begins with (source) and begins with (Target) in fdmee to load to

Hi, gurus,

We have a data load rule to load from EBS to Hyperion Planning for the following logic in the account dimension:

Source    Target  Change sign

------------ ----------  --------------------

5*           5*          Yes

4*           4*           No

What we want is to load all the accounts that begins with "5" and change the signal.

then we want to load all tha accounts that begins with "4" and NOT to change the signal

Please, help me with the correct "Data Load Mapping" for this account mapping.

Thanks in advance
