Hi,
Hope you are trying to avoid duplicate records on the same date. For this the best solution and the effective solution will be managing the records in the pl/sql varaible with the record number.
So that for every when validate record event you can go and check in the pl/sql table for the duplicate record where record number not equal to the current record number.
If you try to navigate between the form records to do the same then unnecassarly the triggers of the corresponding item/record will fire which lead to some exta time. some times this trigger will be irritating.
so try to manage in the pl/sql table and do valide on the pl/sql table in the when validate record trigger.
Note:
you should delete the pl/sql table content in the pre query of the block and you should populate the pl/sql table in the post_query of the block and also in the when validate record trigger of the same block.
make sure ur not populating duplicate rows in the pl/sql table for the same record number.
if the loggic is confusiing do reply.. i will give u a better example.
