Web Dynpro after System Parameter update

[Former Member]

Hello Gurus.

I added 2 additional System Parameters to an Event Handler.

I then transported the changes to QA.

When I ran /saptrx/eh_list I could see the System Parameters were added.

However, when I tried starting the Web Dynpro (/saptrx/em_start) I got a dump.

After 5 hours the Web Dynpro mysteriously started working again!!

My best guess is that the System Parameters were updating the back-end database.

I've noticed the same thing happen every time System Parameters are transported.

I tried running /saptrx/ucpd_delete_obsolete_f and /saptrx/upcd_create but they had no effect.

Any ideas?

Cheers,

Zenon.

Hi Zenon,

after parameter changes it is always necessary to run transaction /SAPTRX/UCCF once, which triggers report /SAPTRX/UCPD_UPDATE. Alternatively you can execute report /SAPTRX/UCPD_UPDATE directly. This will update the web interface parameter dictionary and the new parameters can also be used on the UI.

Cheers, Daniel

Zenon,

Also check that the view on the system parameter table has been created properly.

See the code at line 1373 in /SAPTRX/EH_RETRIEVE_GUIDS where it determines the view name based on the extension table.

Thanks

Kevin

Daniel,

You have to do it through t-code /SAPTRX/UCCF as the program is a module pool program.

Zenon, this t-code deletes all the Info / System and Control parameters (also others like status attributes, tracking IDs, reason codes etc...) from table /SAPTRX/UCCF and recreates them afresh when you call it.
