Naming of Datasources

Question

Hello,
Need some guidance here. I hope to find out why FI-SL DataSource is sometimes named as 3FI_SL_L1 and sometimes 3FI_SL_L1_TT? Or is it due to different naming convention for different releases?
thanks!

Level names can be reused across dimensions. This is common. For example, detail level data is very often shared across levels. When is comes to summary levels, you need decide whether this makes sense. Consider two hierarchies:
Shipping Hierarchy, with levels:
Total Product
Region Shipments
Country Shipments
Warehouse
Item
Product Type hierarchy, with levels:
Total Product
Brand
Group
Item
In the above case, Total Product in each hierarchy should yield the same values because it is the aggregation of all items. So, you might decide that is ok. A different case might not be ok. Consider:
Shipping Hierarchy, with levels:
Total Product
Region Shipments
Country Shipments
Warehouse
Items shipped
Product Type hierarchy, with levels:
Total Product
Brand
Group
Items sold
Since Items Shipped and Items Sold are likely to have different values, the aggregation of each level will yield a different value. In this case, Total Product as the top of each hierarchy doesn't make sense.
A different twist would be (note the display names):
Shipping Hierarchy, with levels:
Total Shipments with 'Total Product' as display name
Region Shipments
Country Shipments
Warehouse
Items shipped
Product Type hierarchy, with levels:
Total Product Types with 'Total Product' as display name
Brand
Group
Items sold
In this case there will be different levels with different values, but the user will see each as 'Total Product'. Only your user community can tell you if this is want they want.
