SAP BW and Spatial analysis

What I learned yesterday and this morning is the usage of maps or other shape based graphics to assign KPI to spatial information like country, region, or places in my factory. To do so one need shape information and assign them to special InfoObjects with geographical features (maintained in rsd1). In BEx Web Application Designer there is a Map web item which displays such data on maps. I could post details on demand. What I want to let you know is that there could be several layers in one map. Each layer is exaclty one DataProvider assigned, and all KPI from that DataProvider are displayed. So if there is the need to display KPI in different manners (like coulored shapes for one and some pie diagram for others) you need to do the following:

1. Set up the query (something maybe done before) containing all relevant KPI
2. Create different query views, each containing interesting groups of KPI
3. Create DataProvider for each query view
4. Cretae map layer for each query view, assing the DataProvider and be creative with all the parameters
5. Save and execute the Web Template
6. Be happy!
