WSDL XML tweak for Essbase Web Services for C#/Service Util

I just thought I’d make a small post on an issue I have encountered with Essbase Web Services. I also mention this during my webinar on the matter. If you use the svcutil.exe program to generate a set of proxy classes based on the WSDL file for Essbase Web Services, you’ll get an error.

At least as it pertains to the DatasourceService file, you need to make a small change. Here’s the problem line:

<xs:element default="DBALL" minOccurs="0" name="cubeAccess" type="tns:CubeAccess"/>

The problem is that it’s trying to set a default value for the CubeAccess property, but DBALL isn’t defined in the enumeration for this type. Here it is from later in the file:

<xs:simpleType name="CubeAccess">
 <xs:restriction base="xs:string">
 <xs:enumeration value="NONE"/>
 <xs:enumeration value="FILTER"/>
 <xs:enumeration value="READ"/>
 <xs:enumeration value="WRITE"/>
 <xs:enumeration value="CALC"/>
 <xs:enumeration value="DESIGN"/>

There’s no DBALL in the above. We can actually just comment out the above line in the file or delete it all together to remove the reference to a non-existing enumeration value. I haven’t seen any problems from doing this. I’m hesitant at this point to try and introduce DBALL as an enumeration value since that doesn’t technically exist in the Oracle definition of the server, and I’m not sure what the right way to go in terms of setting a default value might be (i.e., should it be NONE or READ or other?).

In any case, for the purposes of proxy generation from the Visual Studio tool, just removing the reference seems to do the trick. Here’s what the commented line looks like, just for the sake of completeness:

<xs:element default="DBALL" minOccurs="0" name="cubeAccess" type="tns:CubeAccess"/>

Just tonight I verified that this issue seems to still exist in EPM

That all being said, it’s possible that I’m just totally missing something there – perhaps an option on the proxy generation I need to turn on or something else, but I do know that commenting the line gets me to where I can successfully use the tool. If you’re more familiar with this than I am then please let me know if you have some advice.

Upcoming Webinar: Practical Essbase Web Services

Upcoming webinar, as in happening tomorrow! This webinar will be tomorrow, August 6th, at 11AM PST.

I am conducting a webinar tomorrow called Practical Essbase Web Services. This is mostly a re-presentation of my webinar in New Orleans for Kscope a couple of months ago. As with before, I’ll be taking a tour of the different connectivity options for getting to Hyperion and Essbase data programmatically, then jumping in to the Essbase Web Services component that has started being available as of version

This is a bit of short notice but I wanted to invite anyone that reads this blog to attend. As with my ODI webinar a while back, we’ll be recording it so that it can be watched at your own time, but definitely attend if you are interested in this topic or want to ask some questions at the end.

The link to register can be found here. Wish me luck and I will hope to see you there!
