Hi,
I am using a OVS search help in my application. When I run the application and click on the search help the help opens up , but when I select a value from the search help , I get the following dump:
Type conflict with ASSIGN in program /1BCWDY/7B6BPXV7BTHYS9IXPRJJ==CP .
The code that I am writing is :
declare data structures for the fields to be displayed and
for the table columns of the selection list, if necessary

If phase 1 is implemented, use the field input for the
selection of the table.

Please suggest how to correct the problem. Any pointers would be really helpful.
