Concept of Easy
Queries in SAP BW was introduced in BW
7.3 particularly in SP05 although they were available but not fully functional
in lower SPs like SP02. Another prerequisite to use Easy Queirs is to have BEx Query
Designer with revision of level 671 or higher.
What is SAP BW Easy query?
It allows external access to the BEx queries. By the external access it is
meant here that the BEx query can be consumed by web service. There are other
interfaces that can be used to connect 3rd party tools to BEx
queries, such as: OLE DB for OLAP (ODBO), OLAP BAPI (Business Application
Programming Interface), XML for Analysis (XML/A), OData and finally Easy Query.
First of all such query
needs to be enables for this access. This can be done in BEx Query
Designer. Follow to query properties
and on Advanced tab page for the
query there is a check box in section “Release for External Access” called “By
Easy Query”.
Once the query is enabled
for Easy Query BW system generates configuration needed to access it in BW’s
background. This in particular means that SOA configuration profile is
generated. To see generated objects you can use Easy Query Manager (transaction
EQMANAGER) in the BW system. Note that transaction is webdynpro JAVA based (wda_eq_manager)
so it runs in your web browser via HTTP server built in NetWeaver.
Afterwards the query can be used as a SOAP service. There are certain limitations in this scenario. See full documentation here.
One of common error which
you can encounter while setting flag of easy query in BEx QD is that such a
query will fail while attempt to transport it. There will be following error
while import phase of the transport:
The
easy query is wrongly or incompletely configured Message no. BW_BICS_EQ029
The easiest way to solve
is to uncheck the flag and recollect the query into new transport request.
However if your intention was to use the query for easy query purposes you need
to check the query’s generated objects in TA EQMANAGER.
