Hi All,
The Issue get solved by SAP. Here is the correct answer.
1. Specific to our scenario: We are getting this issue due to the fact one of the portal component EP RUNTIME 7 SP 9 wasn't installed properly in QA. Some of the Ajax framework page Development component of the EP RUNTIME business package was missing in DEV as compare to QA.
So SAP has suggest to reinstall the EP RUNTIME 7 SP9 Business package as per the steps suggested in note 1921719. Which has solved our problem.
Option 2: AS suggested by SAP that ~singletransaction is not supported by portal, it is recommended to copy the Webgui service to a new service( 1 or more) and maintain all desired parameter for each transaction that you want to integrate or accessed from portal.
Example. You have 2 transaction to be integrated in portal Z1 & Z2
Now copy Webgui service from ITS to new Services Z1_gui & Z2_Gui and maintain the required
configuration parameters.
Z1_GUI
~singletransaction 1
~transaction Z1
....
....
Z2_GUI
~singletransaction 1
~transaction Z2
Activate the services above.
Part 2: Now instead of creating transaction iview in portal, you can created IAC iview refering to these services and this has solved my Webgui click issue.
Thanks again for all experts who suggested me the solution in this forum.
