Error in retriving the saved pdf reports in crystal web service in APP8

Hi Pankaj,

Welcome to the IFS community !! 

It's always better to check the crystal web service log files. Since you are in APPs8, there is a possibility that logging functionality could be unavailable as it was introduced later along with a patch. Please check whether CR_Web_Log.exe is there in the Crystal Web service installation, the n you could enable logs in following way and troubleshoot the issue.

This error seems to a generic error you get when there is a issue in crystal reporting. However more specifically for this error, there is a known limitation involve to this error. If you perform multiple report requests to the same crystal web service simultaneously, you can get the Error in retrieving the saved PDF report from Crystal Web Service exception. 
Was there a similar kind of situation where you had to order multiple reports at the same time? 
If this is the relevant scenario, probably this could be due to limitation is due to an error in Crystal Runtime. Well.. to address this issue, IFS has provided a patch to fix this issue. 

Meanwhile please check following. 

1. Check if the Oracle Client version matches the database version.
2. Check if the Oracle Client bit version (x86 or x64) match with the machine's OS's bit version.
3. Check if you have installed both versions of the .net runtime. There should be only one version. 
4. Check if the tnsname in the tnsnames.ora matches the ORACLE_TNS in the configuration XML.

Last not the least, if this happens to be a issue occured only for a particular report.. you will definitely have to review the report layout whether it is developed correctly.

The F1 documentation I have provided as the link and a pdf attached are for APPs 8.

The video links are not specifically targeted to APP8 but the troubleshooting is more or less similar in each tracks..

So you would be able to find a clue to your problem with them. :)  

In case if you can not find logging functionality available in the crystal web service installation, there is a patch provided by IFS for APP8 to have this option. You could go for it as well..
