Error :Value of restricted LOV parameter not among the selectable values

Question

Hi,
I am designing a report which has two layouts. I have a parameter :P_Reason_code which is applicable to only one layout.
There is a repeating frame in my first layout which should display only if :P_Reason_code value is 'Y'.
I have wriiten a format trigger for this repeating frame saying the repating frame should return true if :P_Reason_code value= 'Y'.
else, it should return false meaning it shouldnt display.
:P_Reason_code is an optional parameter when i run it at the oracle apps front end.
The problem that i am facing is that when i run the report for the second layout by not providing value for the parameter :P_Reason_code
, it errors out saying "REP-0788: Warning: The value of restricted LOV parameter P_REASON_CODE is not among the selectable values.'
I tried creating another user parameter P_REASON_CODE1 and putting a trigger in the After parameter form trigger saying
if P_REASON_CODE is null then
P_REASON_CODE1 :='Y';
P_REASON_CODE := P_REASON_CODE1;
ELSE
P_REASON_CODE1 := P_REASON_CODE;
P_REASON_CODE := P_REASON_CODE;
END IF;
But still it doesnt seem to work.
What could be the issue?
Can anyone help?

Answer 1

try setting the default-value for the parameter to Y (or whatever value is in the LoV defined for the parameter).
Is there a parameterform used for the report. If not remove the LoV from the parameter.
