[Former Member]

Hi All,

I have used enhancement set to add context node 'BTSubject' in BT160I_CPL/ComplItem view and got exceptions in webclient complaints screen. So i deleted this enhancement in BT160I_CPL/ComplItem, since then i have been getting the following error in the webclient complaints screen.

_______________________________________

Cannot display view BT160I_CPL/ComplItem

An exception has occurred Exception Class CX_BSP_INV_ATTR_NAME - BSP exception: An attribute with the name "BTSUBJECT" is not defined

Method: CL_BSP_PAGE_BASE=>IF_BSP_PAGE~GET_ATTRIBUTE

Source Text Row: 17

Hi guys,

After enhancement set was deleted for the component BT160I_CPL view ComplItem and run it from BSP_WD_CMPWB transaction, it throws the following error.

Hi Krish,

after I read the message I was curious and had a look in our, never enhanced, CRM system. Component is BT160I_CPL.

When I have a look at the component controller its implementation class is CL_BT160I_C_BSPWDCOMPONEN_IMPL. It is inheriting from its super class and then from the SAP standard controller class.

Now in the MainWindow's implementation class there is the method from the dump you gave IF_BSP_WD_STATE_DESCRIPTOR~GET_MAIN_ENTITY(). In this method a variable lr_comp is declared of type CL_BT120H_C_BSPWDCOMPONEN_IMPL. This class is NOT a parent class of the component controller mentioned before.

Thus the type cast in the second line fails. As it is not handled in any way (Yes, it seems SAP hates error handling) you get your dump.

Now as the system in which I check is and was not enhanced this is a general bug. Type casting incompatible types will never work.

My suggestion: Raise a CSS Message! After you get a note please post it here.

Hi Krish,

Please note that there is a SAP note (1122248) to delete the enhancement set. If you don't use it and deleted the enhancement set, than may be your component runtime repository file got deleted. Solution is, you have to copy the runtime repository back to the same component. Please dont ask me - how to copy a runtime repository or from where to copy a runtime repository - as we had the same problem and SAP helped us. I asked them the same question/s without answers...

Hey Krish,

Go to the HTM Page of your view and click on the "Page Attributes" tab. If you find BTSubject there, please delete it.

This could resolve the issue.

Hi Krish,

I assume that you did not delete all the generated coding.

Check first off all the attributes of the html page for the BTSubject one.

Then in the controller of the page check the set_models method.
