Hallo,

I have master and 2-detail blocks,
in detail block, i have WNRI- Trigger, which is as below, and these two blocks display records when the criteria matched (which is defined in WNRI in master block), either just in one block or in both blocks, as per the matched criteria.
and when the search criteria has matched just one and display the record in the respective blocks, but the problem i am having is, when i click to the above block in ID field then, it gives error:
"FRM-41803: No previous record to copy value from "
though the criteria is matched just the block below. I actually looking for that, when just criteria for block2 matched then it should display records in block 2 and the block1 should be deactivate or not allowed to click.
how can i solve this error? help please.

in detail blk:

if :system.record_status = 'NEW' then
	duplicate_record;
  set_block_property('block1', INSERT_ALLOWED, PROPERTY_TRUE);
	:block1.id := null;
end if;

regards,

Well, maybe the simplest option would be to trap FRM-40803 in ON-ERROR or ON-MESSAGE trigger (I don't know what it really is - an error, or a message - you'll find that out). Something like

if error_code = 40803 and error_type = 'FRM' then
   -- do nothing, ignore it
   null;
end if;

Otherwise, if you want to disable the whole block, you'll have to do it item-by-item (as you can't set such a property for the block itself; at least, unless I'm wrong). That would require some more typing as you'd have to disable all items and enable them back when necessary.
