Generating Master Data Values programatically

Hi,

     I have a flat file with just descriptions and I would like to load these and have Master Data ID automatically created.

So for InfoObject Bike Style  I would like to load the text and have Master Data ID's generated like BR00001, BR00002, BR00003.

So for InfoObject Bike Category I would like to load the text and have Master Data ID's generated like BC00001, BC00002, BC00003.

I'm thinking this might be possible using Number Range Functionality, but I thought there might some existing BW code out there for this someone might have seen?

Any thoughts and opinions are greatly appreciated!
