"Shouldn't we put all this information into a book?"...
...that’s how we started more than one year ago and now the book is finished and available for sale. 
Berechtigungen in SAP NetWeaver BW
We have attempted to bundle all the information covering authorizations within SAP NetWeaver BW systems into this one book. Subsequently the book has turned into an extensive reference source for information relevant to authorizations in BW.
Our main focus was initially the analysis authorisations. However we also covered the standard authorisations which are relevant for data extraction, data warehousing and the area of report creation/execution.
The concept of authorizations within SAP BW is not difficult to understand, however the "nature" of OLAP like authorisations is a little more complex, since they are not transaction based (which is the usual method in SAP systems) and thus the users selection during query navigation can change with each single navigation step.
Throughout the years working with SAP BW authorizations systems we have noticed that large BW installations become either sooner or later harder to administer. This is the result of evolving BW systems and the fact that InfoObjects are subsequently defined which cross the system in different data models. Thus the changes to hierarchies or characteristic values, requires more effort on authorisations than expected and therefore the administration of such systems becomes more costly.We have tried to point out which are the major factors to keep analysis authorisation relatively easy to implement, expand and maintain.
The book begins with an easy introduction with examples for authorisations and later provides more detailed technical and conceptual information for setting up a sustainably running authorization system.
