Hi Praveen,
I have appended the new attribute to the structure, get the same error. When I debug method
SET_PROPERTY_AS_STRING in class CL_BSP_WD_VALUE_NODE.
The issue seems to in the code below.
assign ME->DATA_REF->* to <DATA>.
assign component LV_ATTR_NAME of structure <DATA> to <VALUE>.
The structure <DATA> does not include the new attribute hence the error in the assign statement.
Regards
Chan
