Put a break point in CL_BSP_MODEL=>IF_BSP_MODEL_BINDING~IS_ATTRIBUTE_VALID   and step through 'till it creates dump.  You should be able to figure out what the issue is.  Check both runtime repository editor and component structure browser for modelling correctness.

Seems you are trying to access attribute which is not available as a part of BOL entity. Please chek.

Hi,

I'd suggest you to check that your context, context node and controller classes if they were properly activated. The names of context and context node classes are generally hardcoded. Please check that it corresponds to the one you have.

If nothing works, set a break-point at the method IF_BSP_MODEL_BINDING~IS_ATTRIBUTE_VALID of class CL_BSP_MODEL.

Check whether 'CATEGORYDESC' is a correct attribute name

Hi Rose,

It means you are trying to read an attribute CATEGORYDESC which is not available in the current entity structure. What is the context node you enhanced? If it is BTADMINH then the attribute available is CATEGORY and not CATEGORYDESC.

There is some problem in enhancing BT126H_APPT/ApptDetails. And it seems to be with attributes added, could be the methods generation process. Click on the methods of attributes you created and see if all of them are present in context node class CN* of the node where you created custom attributes.
