SAS VA Warning: The server did not understand the application request for data

Hi Experts,

 

Good day!

 

Anyone here encountered warning message: "The server did not understand the application request for data" and what is the solution?

 

FYI. We encountered the warning message when we print to pdf the Custom Graph. Please advise. Thank you so much.

 

 

Best Regards,

Hi Carrot17,

 

The error message you are getting is reported to also be an issue when rendering a report in the SAS Mobile BI app that uses parameters. There is a hotfix for it for SAS VA 7.1. http://support.sas.com/kb/55/609.html

 

Some questions to consider:

  • What version of SAS VA are you using?
  • What browser are you using - type and version? Do you get this message across different browser types? (If you haven't tried, please try it.)
  • Does the Custom Graph you're trying to print to .pdf use parameters? If so, can you print to .pdf another object that doesn't have parameters.
  • What is the underlying Custom Graph object type? ie/ bar chart etc?
  • Have you looked at the server log files? What are the messages around the same time you access the report?

 

Some basic troubleshooting is required to isolate the issue in an effort to work out the cause of this generic message. This is something that would be helpful to also pass onto SAS Technical Support if you decide to go down that path.

 

Kind Regards,

Michelle

Re: SAS VA Warning: The server did not understand the application request for data

Hi Carrot17,

 

Thanks for your reply and actions.

 

It seems that your report may be rather complext with may custom graphs and parameters and filters. Is there interactions as well? It could be the unique combination of objects/parameters/filters/interactions that is causing the error or it could be the custom graph object.

 

If you create a new report with the Custom Graph object you are trying to print and attempt to print it to .pdf? This will be an isolated test to see if there is something with your custom graph object. If you get no error it might be due to the combination as I mention above.

 

In any case, it would be good to see if there are any messages in the log and potentially raise it with SAS Technical Support, you could send them a link to this post and your log file.

 

Kind Regards,

Michelle

Re: SAS VA Warning: The server did not understand the application request for data

Good afternoon,

 

We had similar errors within one of our reports and we found the root cause in the dataset. When your dataset contains records which has a longer length then the set length/format in the data builder.

 

What I did do find the causing record(s) was narrow the filter in the visual and increase till the error appeared.

 

Good luck

Hi EWS,

Thank you for sharing. Anyways, What do you mean with longer length? Length of Column Name or Data itself?

Re: SAS VA Warning: The server did not understand the application request for data

Hello Carrot17,

 

What I mean is, when the length of the data itself is longer as the set column length. 

 

Normally the column length is set automatically when adding a column to the dataset in the data builder this is depending on the source data . But you can manually override this or and this happened with our data the source data was changed after the initial query was build which caused the error. After increasing the column length in the data builder and run the query again all errors where solved.

Re: SAS VA Warning: The server did not understand the application request for data

Hi,

I tried to create a simple custom graph and used same data source/data item without changing in the data set length, the custom graph can print. however, when custom graph has 2 or more graphs combination it can't print. Thank you.
