Hi Kiran,
I tried the following options based on your suggestion.
1. I used the get_attribute method as suggested by u and i was able to fetch the value for the attribute WRKDESC sucessfully.
2. I later changed the cardinality of node N_NATURE_COMPL to 1...1, deleted the drop down by index and created an input field and assigned the attribute WRKDESC to the input field. I then used the get_attribute and the REPORT_ATTRIBUTE_ERROR_MESSAGE. I was able to generate the error message as well as highlight the field in red.
Thanx
Regards
Ekalavya
