Transfer rule question

Hi

We are using 3.x transfer rules for our 0PROFIT_CTR attribute data load.

we are bringing one new field from ECC to BW system.

From ECC we are getting the field as 201RXX which is having 13 characteristics length.

In BW in trasnfer rules we need to map this field to the 2 info objects.

To the one info object we need to pass first 3 letters of the field we are getting in above case we should pass 201.

To another object we need to pass remaining all letters of the the field in above case we should pass RXX.

Please share your thoughts how we can easily achieve this.

Thanks

Vijay
