Overview and Details


There are 2 types of OData Queries:

The transient analytic query generation and the OData service generation is executed automatically, so one can use the service almost(apart from releasing the service in /IWFND/MAINT_SERVICE → package assignment)  without additional manual steps.

  • /IWFND/GW_CLIENT  -  for testing the service
  • /IWFND/MAINT_SERVICE  -  list of all released services
  • /IWFND/APPS_LOG  -    SAP Gateway Application Log Viewer
  • /IWFND/CACHE_CLEANUP  -  Cleanup of GW Model Cache
  • /IWFND/CACHE_REBUILD  -   Rebuild Gateway Model Cache
  • /IWFND/ERROR_LOG    -   SAP Gateway Error Log
  • /IWFND/TRACES  -  SAP Gateway Tracing Tools
  • /IWBEP/REG_SERVICE - Maintain Service
Most important URI parameters 


get e.g. name of fields(infoobjects) and variablesExample III
../AdditionalMetadataget queryname, query definition timestamp, data refreshtimestampExample
../QuerynameResults   resultset without variables  for BEx QueriesExample II
../viewnameresultset without view parameters  for CDS based QueriesExample I
../QuerynameResults?$inlinecount=allpagesresultset with linecount (number of rows returned by the query)Example IV
../Queryname(var1=value,var2=value,...)/Resultsresultset with variables (single selection)



resultset with date / time variables
  • datetime'2019-06-16T00:00:00' = June 16th 2019
  • time'PT19H05M05S' = 19:05:05
../QuerynameResults?$select=char1,char2,keyf4...reduced resultset output size via fieldselection
../QuerynameResults?$filter=char1 eq 'value'reduced resultset output size via filter
 $order_by=char desc/ascsorting of values works similar to BW queries, see exampleExample VIII(OData CDSquery)
Important Points & Topics
  • Bex Variables
    • The technical names of the Bex variables need to be specified with capital letters, see ODATA query with variables.
    • In case no variables at all are specified in the URI('Results') the system uses the default values if available. When mandatory variables remain empty the error BRAIN 629 occurs, see also Example IX.
    • If variables should/need to be specified in the URI then all variables have to be filled, even when they should be left empty, see Example III and Example IX.
    • For interval variables both the From and To Fields must be filled, see ODATA query with variables.
    • Only one default value is shared per variable in case of a meta data call($metadata), see Example IX.
    • Only default values defined in query definition are exposed in a meta data call($metadata), values that are determined at runtime (e.g. via customer exit at i_step=1) cannot be exposed in this case. See Example IX.
  • Parameter $select: it defines the drilldown; if not specified, all InfoObjects/Fields(including free characteristics) and key figures are put into the drilldown! (memory/performance issue!)
  • The URI parameters are case sensitive! Hence always use the exact technical names of the parameter values as listed in $metadata(e.g. for the query and variables). See e.g. ODATA query with variables.
  • OData CDS Query: the order of the Infoobjects in the drilldown is defined in the CDS view, the order in the URI is irrelevant.
  • OData Easy Query: the order of the Infoobjects in the drilldown is defined in the Query(free characteristics are not taken into account), the order in the URI is irrelevant
  • OData CDS Query: parameters are always mandatory and hence have to be filled by the URI: see Example VI.
  • BW OData Queries: Hierarchy-Handling
  • Analytical OData V4 services are not supported at the moment. It will be only available for OData CDS Query in the future S/4 releases.
  • As a prerequisite certain settings have to be maintained in the BW backend system which can be done with the help of report EQ_RS_AUTOSETUP, see 1944258 for further details.
