Transformation help BPC 7.5 NW

Question

Hello Experts,
We are on SAP BPC NW 7.5 SP08
I am looking some help in maintaining the transformation file.
I am loading data from application to another application using load data using Load data from Info provider with selection package.
My source location has length of 12 (example : 10-1000-A080) when i am mapping to my target i need to load last four (i.e A080). My source technical object name is /CPMB/Q3IESYO
Transformation file:
LOCATION = /CPMB/Q3IESYO  ( but I need to load only last four char.)
When i load similar using flat file with out header then i can use like LOCATION = *COL(5,9:12).
I know we can use conversion file here but that is throwing some error so i am looking is there any option without using conversion file.
Thanks,
Sri

Hi Sri,
You can use the JavaScript Conversion functionality in order to achieve this. It is documented on help.sap.com.
http://help.sap.com/saphelp_bpc75_nw/helpdata/en/bpc_nw_index.htm
Data Management-->Data Conversion Maintenance
In the text there is a section on this Titled - Javascript can be used in the data conversion
See the excerpt from help below which directly addresses your issue:
Javascript can be used in the data conversion
    Mandatory: Precede the Javascript code with the following string: js:
    You can use Javascript code in IF statements.
    Example Example
    The following examples illustrate Javascript string manipulation commands:
        js: %external%.substring(0,2)
            This example returns a substring of the string contained in external.
You would use the above substring JavaScript method to grab the last characters of your member value. If you have varying string lengths you would need to use this in conjunction with the string length function in JavaScript.
You could also achieve this by using a start or end routine BADI....
