Loading hierarchy from r3 to BW

Question

Hi,
I am trying to load a hierarchy from R3 to BW, but once in BW i do not see any hierarchy.
I have checked if the hierarchy was activated in R3 and it is, do you know any reason or solution?
Do you know where I can find information about the steps to follow?
Many tahnks

Hi,
Say you want to extract an existing hierarchy from an SAP R/3 system and load it into BW so you can present your reports in a hierarchical way. For example, by loading a cost center hierarchy into BW, you could show expenses at the top node and then drill down to the lower nodes to see the details.
Although standard Business Content extractors support main hierarchies (e.g., cost center, general ledger [G/L] account, material, plant, work center), they do not support all hierarchies in the R/3 source system, such as Treasury Cash Management. In this case, SAP does not provide a standard DataSource to link R/3 hierarchies to BW.
So what are your options? In my example of working in Treasury Cash Management, you could define hierarchies for planning levels and create your own ABAP program to extract the data from R/3, send it to a flat file, then upload the flat file into BW via a custom DataSource, a multistep process. This is what I call the “traditional” method.
I developed a workaround that allows you to bypass the step of creating a flat file and extract directly from R/3 in a single step, like any Business Content DataSource. My workaround combines two different standard SAP mechanisms: the generation of a hierarchy DataSource on the R/3 IMG side and the user exit EXIT_SAPLRSAP_004 on the R/3 side. I tested this workaround with BW 3.5 and plug-in (PI) 2004-1, but it also works with BW 2.0B with PI 2002-1 and later.
Hope it helps.
Thanks,
