Hi Raf,
Thanks for your comment.
You are absolutely right the capability of using custom built R functions in SAP Predictive Analysis is enhancing the functionality to a completely new and better level.
Regarding your second point on error messages. I am sure you know this but SAP PA generates a logfil that is default stored in %TEMP%\sapvi\logs
This logfile shows in more detail what is going on and could also assist support if you create an OSS message.
If you want need more information you can change the logging details as described below (from Vishwa' blog on tracing):
1. Create a folder in any location for generating logs.
Note: Ensure that you have "write" permission to the folder. For example, C:\logs.
2. Create the BO_Trace.ini file and add the following trace details to it.
active=false;
severity='E';
importance=xs;
size=1000000;
keep_num=437;
alert=true;
Save and close the BO_trace.ini file.
4. Place the BO_Trace.ini file under C:\logs.
5. Set up the following environment variables:
• BO_TRACE_LOGDIR = C:/logs
• BO_TRACE_CONFIGDIR = C:/logs
• BO_TRACE_CONFIGFILE = C:/logs/BO_Trace.ini
6. Restart the application.
Hope this helps you out.
Best regards,
Kurt Holst
