hi sander, i have see these, and tried to understand many more like this, but i still get confused.
lets say, i have a transaction data source coming from sap erp - 0FI_GL_XX, this is loaded into a DSO - ZFIGL.
I wish to report off this DSO as usual business throughout the years to come.
which layer would i put the DSO in?
1. Open ODS
2. EDW
3. Corp Mem
