I am trying to follow the following instructions:
[Uploading Hierarchies from Flat Files|http://help.sap.com/saphelp_nw04s/helpdata/en/fa/e92637c2cbf357e10000009b38f936/frameset.htm]
I am new to SAP BW and find the instructions very hard to follow. The instructions seem to expect me to know a great deal more than I actually do at each stage. I have created a Flat File (.CSV) with the columns specified (NodeId, Iobjnm, etc) but I don't understand the relationship of Datasources, InfoSources etc on the way to actually getting the Hierarchy loaded into my InfoObject.
I have just about mastered the process of loading data from flat files through InfoPackages, DataSources(7.x), DSOs, Transformations and on to InfoCubes. So I understand the basics of creating InfoObjects and Transactional and Master Data.
Any advice, more detailed instructions welcome.
