OLAP Authorizations

Introduction

All users who want to display transactional data from authorization-relevant characteristics in a query require analysis authorizations (or OLAP authorizations) for these characteristics. Analysis authorizations are NOT based on the SAP Standard Authorization concept. They use their own concept based on the BW reporting and analysis features. Please have a look at note 820183 which provides an overview and description on how the authorization concept works.

Important to Know

The OLAP-authorization-check must not be confused with the basis-authorization-check. When executing a BW-query some basis-authorizations are checked first. f.e. S_RS_COMP1, S_RS_COMP (authorization for executing a BW-report, see note 540720), ..etc. If the basis-authorization-check is successful, the OLAP-authorization-check (which checks the analysis-authorizations) is performed.
It's very important to understand that the OLAP authorization-check is executed before the data are retrieved from the database. It checks whether the assigned authorization-set authorizes the selection-set of the query. The selection-set comprises of all the filters/restrictions applied in the query. If the selection-set is bigger than the authorization-set, the user will always get an authorization-error. It is irrelevant whether authorized values are booked in the infoprovider.
OLAP authorizations do not act automatically as filter restrictions in queries (this is only possible with the "thinning-out" feature described in note 1905641). If this is required you need to use variables filled by authorizations. However please read note 1736473 which describes possible problems when using authorization-variables for multidimensional authorizations.

The old authorization-concept in BW 3.X has been completely replaced by the new 7.X authorization-concept introduced with BW 7.X. This site will only deal with the new authorization concept as the old authorization-concept will no longer work in future releases (see note 923176).

Runtime of the OLAP authorization-check

The figure shown above roughly shows how the authority-check is carried out executing a BW-query. The runtime of the authority-check also involves checking the authorizations for the infoprovider and retrieving the assigned authorization-values. The query in the example is very simple not using any variables/hierarchies/complex OLAP-features etc.

Step 1: The query is executed with a selection defined in the query-definition

Step 2, 3 and 4: The authorizations for all authorization-relevant attributes used in the query are collected and filled into the authorization buffer. Note 1951019 provides more details on attribute authorizations. The auth-relevant attributes for which the user is not authorized are simply not getting displayed in the BW report.

Step 5, 6, 7 and 8: The authorizations relevant for the infoprovider are collected and filled into the authorization buffer. The system then checks whether the user is authorized for the infoprovider on which the query is based. Note 2504860 provides more details on the infoprovider-check which is the first part of the OLAP authorization-check.

Step 9a: The query displays an authorization error if the infoprovider-check in the previous step fails.

Step 9b and 10: The system now continues with the main authorization-check checking the selection-set selected by the query in Step1. If the selection-set is greater than the authorization-set, the authorization-check fails.

Step 11a: The query displays an authorization error if the main authorization-check in the previous step fails.

Step 11b, 12 and 13: If the authorization-check is successfull, the system continues retrieving the selected data from the database. It's very important to understand that the OLAP auth-check is done before the database is accessed. Hence the idea that authorizations work as filters is not correct. Authorizations do not automatically filter the data according to the authorized values. The authorization-check simply checks the selection-set (regardless of whether data exists for this selection).
