Hi friends, i am developing a report in oracle applications where the report contains 4 parameters as follows parameters date option: - lov “as of date’ and “range” as of date start date end date depending on the value of date option the following fields should enabled. E.g. Suppose user has selected the date option as “as of date” then he should be able to enter the value of “as of date” only and not in start date and end date and vice versa. Pl.let me know if you have any solution for this. Thanks & regards viajy gurme
