Export to pdf cache problem using custom URL

[r_hilbrands]

Hi,

Strange problem. We are running BO4 SP5 patch 3. Users are visiting Launch Pad using a custom URL (like http://reports.companyname.com). This is done with a DNS record.

BO is also reachable with the original URL: http://bo4-servername-prod/BOE/BI.

Problem:

We open Launch Pad using http://reports.companyname.com. Then open a Webi report with a prompt. Refresh it and click export to PDF (using the print or export-button). A PDF-file is generated and opened in Adobe reader.

We close Adobe Reader, go back to BI Launch Pad and refresh the report with different prompt values. Again, we click 'export to pdf' and a pdf file is opened in Adobe Reader, but with still the old report data from previous refresh. Even when refreshing and exporting the report again, the PDF-file is still showing old data. When trying it again after a few hours the pdf is refreshed the first time, but again after refresh and exporting the report, it shows the older version.

When opening Launchpad using the original URL http://bo4-servername-prod/BOE/BI there is no problem and the PDF-file is always showing the same as in Webi. So I don't think this is a IE or Adobe caching problem.

It looks like the problem is related to this custom URL and cache. Does anyone else have this same problem with a custom URL? Is there a solution for this?

I think I found the cause of the problem. In the web browser there is a proxy configured. In the proxy settings of internet explorer I made an exception for reports.companyname.com and everytime the updated version of the pdf is shown now. Probably the proxy server caches pdf files from 'internet' URL's and not from local URL's.

Hi Hillbrands,

                    Have you found the solution to this issue? I checked for proxy settings on my browser but I don't seem to find any here. I checked on Chrome and IE10. We're on BO 4.0 SP6. I'm having the same issue exporting out to PDFs.

In my case the solution was to disable the proxy. Maybe in your network there is a transparent proxy (http://en.wikipedia.org/wiki/Proxy_server#Transparent_proxy) or something like that? You could consult your network administrator.

Hi Vijay,

We have tried everything but unfortunately we still have the same problem, have you solved your problem?

Hi,

Can you set your IE -> Tools -> Internet Options -> Settings and choose "Every Time I visit the webpage" and reduce the disk space to 8 MB?

Hope this helps,

Unfortunately this doesn't help I think it's some sort of caching problem in BO. I also tested logging in on another computer. When refreshing the report, I see a pdf which I refreshed on the other computer.

Hi Hilbrads,

You may need to clear the cache at client side. Check if this could help you.

Thanks for your reply. I cleared the cache client side, but with no result. I still think it's a problem in BO, because even when logging in to another machine (with different web browser and pdf reader) the old version of the PDF is shown.

This only happens when using the custom URL.

[denis_konovalov]

do you by any chance have SSO when going thru this custom URL ?

based on description of the problem it does not look to be a simple dns redirection. there are more things with this URL you're not telling us.

If you want to resolve this quickly - open a support Incident with SAP.

[r_hilbrands]

Yes, we are using SSO. And it 's only a simple DNS redirection. As far as I know there are no things I am not telling you

On another forum I read someone else has the same problem, so probably it's a bug...
