start routine to load highest Pos-Level Nr. for every Business Partner

Hi

I have the following issue where I need to load the data record with the highest position-level for every Business Partner from a DSO to an Info-Cube.

The records in the DSO are as follows...

BP-Nr...............Pos-Level

1001......................1

1001......................2

1001......................3

1001......................4

1002......................1

1002......................2

I need to load only the following records in the Info-Cube

BP-Nr...............Pos-Level

1001......................4

1002......................2

Could you pls help me with the ABAP coding.

Many thanks,

SD
