Dynamic Prompt Issue

Question

Hey hi I am just working with Dynamic prompt my requirement is
> When I select country name from ddl i.e India, In the next state field I want to get prompt table regarding indian states
When I select country name from ddl i.e usa, In the next state field I want to get prompt table regarding usa states For this I have created two views on PS_STATE_TBL , to use for prompting
india
SELECT DESCR FROM PS_STATE_TBL WHERE COUNTRY ='IND';
usa
SELECT DESCR FROM PS_STATE_TBL WHERE COUNTRY ='USA' AND DESCR NOT LIKE '%tax';
Next I have written the following code in FieldChange event Evaluate DYNAMIC_TBL1.COUNTRY1
When "I"
DERIVED.EDITTABLE = "RECORD.INDIA_PROMPT_VW";
Break;
When "U"
DERIVED.EDITTABLE = "RECORD.USA_PROMPT_VW";
Break;
When-Other
End-Evaluate;
But from the front end I am getting the following error message
Prompt table in the DERIVED.EDITTABLE is not available. (4,3)
the prompt table for the field for the field is controlled by the contents of another field. this controlling field is not included in the component.

Raju,
What do you think about creating a UNION SQL view that has a key field COUNTRY1 with values of I, U, etc? Your view SQL would look something like this:
SELECT 'I', ...
  FROM INDIA_PROMPT_VW
UNION
SELECT 'U', ...
  FROM USA_PROMPT_VW
...By making the field a key in the prompt, the component processor will automatically add a WHERE clause restriction as long as DYNAMIC_TBL1.COUNTRY1 is listed in the buffer earlier than the prompt field. This works the same way as SETID/BUSINESS_UNIT.
