Hierarchies in SAP BW

Hi all,

There are no Material hierarchies set up in the ECC system, however we are required to do the following:

1. Find all Materials that end with a "Z" (for example , 78880Z) and make it parent (Skip all materials that do not start with a Z)

2. For children ,look for all materials that have a / after the "Z"  material and include them as children

Example:

78880Z

•      7880Z/01
•      7880Z/02
•      7880Z/03

How can this be achieved in the BW system?

Cheers
