Hi All,
I am working Oracle forms 10g.I do have a master detail form . Master block is based on cards table and the detail block is based on Transactions table.
The detail block has a database column - Reviewed which is a check box.
For example,if the detail block had 4 records and the if the user checks the item 'Reviewed' for 3 records, when the user clicks the save button at the top ,
an alert should pop up.

I have set up an alert for the pop up message.
But my issue is that the pop up message is coming up all the time when the user clicks save button all the time.
Please help.

Thanks
Megha

Where did you put your code for the Popup (Alert)? Can you give a code sample?

Hi Craig,

I have the following in the when-checkbox-changed trigger at the form level.

 if   :trans.reviewed_flag = 'Y' THEN
              
                cl_button := Show_Alert('caution');                 

                                     IF cl_button = ALERT_BUTTON1 THEN 

                                          :trans.reviewed_by := v_fullname;

                                   Set_Item_Instance_Property('TRANS.REVIEWED_FLAG',CURRENT_RECORD,UPDATE_ALLOWED,PROPERTY_FALSE);                          

                                      ElSIF cl_button = ALERT_BUTTON2 THEN

                                           Set_Item_Instance_Property('TRANS.REVIEWED_FLAG',CURRENT_RECORD,UPDATE_ALLOWED,PROPERTY_TRUE);       

                                            :trans.reviewed_flag := 'N';

                               END IF;

               end if;

on the property palette of the alert button , I have set the Button 1 Label as OK ; Button 2 Label as Cancel. Default Alert Button is set to Button 1.

Once the user checks the reviewed check box and it is saved to the database , the user cannot uncheck the reviewed check box.Hence the code.

Thanks
Megha

But my issue is that the pop up message is coming up all the time when the user clicks save button all the time.

Of course; you told it so. If you don't want to raise an alert every time you click a checkbox, then remove alert from the WHEN-CHECKBOX-CHANGED trigger and put it somewhere else.

Hi Littlefoot,

What is the correct trigger to be used? I thought when checkbox changed trigger is fired when there is a change on the checkbox item. Though the user did not change the checkbox, it is still firing. Please suggest the correct trigger .

Thanks

when-checkbox-changed only fires when a checkbox is changed. If it's firing when the user doesn't change it then some other code is changing it.
What does this alert actually say?

Hi Cookiemonster,

The alert is a message saying 'By clicking the reveiwed flag, you have reviewed the relevant transactions'.
Can you please suggest the right trigger ? All I am trying to do is if the detail block had 4 records and if the user checks the item 'Reviewed' for 3 records, when the user clicks the save button at the top ,
an alert should pop up.

Thanks
Megha

If you want the alert once per record - pre-update. If you want it once per save - pre-commit.

Thank you Cookiemonster.
The pre commit trigger works as per the requirement as in it fires only once when I hit save.
This is the code I have in the pre commit trigger at form level.

declare
		cl_button NUMBER;
		v_fullname pcard.transactions.reviewed_by%type;
		v_userid   pcard.transactions.reviewed_by%type;
		
begin
	 
v_userid:=FND_PROFILE.VALUE('USER_ID');

select hr.full_name into v_fullname
from hr.per_all_people_f hr,
     applsys.fnd_user fnd
WHERE (hr.person_id = fnd.employee_id)
and fnd.user_id=v_userid
and hr.effective_end_date > sysdate;


  if   :trans.reviewed_flag = 'Y' THEN 
      	
      	cl_button := Show_Alert('caution');
      	 
      	
 	   	     IF cl_button = ALERT_BUTTON1 THEN  
 	   	          :trans.reviewed_by := v_fullname;
 	         	    Set_Item_Instance_Property('TRANS.REVIEWED_FLAG',CURRENT_RECORD,UPDATE_ALLOWED,PROPERTY_FALSE);    
 	   	
 	   	      ElSIF	cl_button = ALERT_BUTTON2 THEN
 	   	            Set_Item_Instance_Property('TRANS.REVIEWED_FLAG',CURRENT_RECORD,UPDATE_ALLOWED,PROPERTY_TRUE);   	
 	   	            :trans.reviewed_flag := 'N';
 	        	END IF;	
 	end if;
 end;

Since, I want all the 3 out of 4 records that have 'reviewed' checked to be saved to the database I put the following code in pre -update trigger at form level.

update transactions
set 
reviewed_flag = :trans.reviewed_flag,
reviewed_by = :trans.reviewed_by,
last_update_date = sysdate
where transaction_id = :trans.transaction_id;

But it is updating only one record to the database. Which trigger should I be using to update all the 3 records to the database ? and also once a record has been saved to database as checked, it should not be unchecked again.

Please help.
Thanks
Megha

Hi All,

Thanks for all the help. I resolved this using the pre update trigger and the pre commit trigger. I have the code for the alert message in the pre commit trigger and the code to update the database is in the pre update trigger and it works.

Thanks
Megha
