   Loop
      null;
      if :system.last_record = 'TRUE' then
         exit;

I have 2 Block Block1 and Block2
In Block1- 2 Column Column1 (Primary Key Set to Yes) and Column2 (Block1 Property Set to > No of records Display '20')
and 1 Button (Display Set to 1)
Query Data Source Type-- FROM clause query and Query Data Source Name-- SELECT * FROM DUAL;
In Block2- 1 Column Search

When-New-Form-Instance

DECLARE
	v_query VARCHAR2(50);
BEGIN
	v_query := '(SELECT code, name FROM mast)';
	Set_Block_Property('Block1', QUERY_DATA_SOURCE_NAME, v_query);
	Execute_Query;
END;

When-Button-Pressed

DECLARE
	v_query VARCHAR2(50);
BEGIN
	IF :Search IS NOT NULL THEN
		First_Record;
		LOOP
			Next_Record;
			EXIT WHEN :SYSTEM.CURSOR_VALUE LIKE :Search;
			EXIT WHEN :SYSTEM.LAST_RECORD='TRUE';
		END LOOP;
	ELSE
		Raise Form_Trigger_Failure;
	END IF;
END;

But i want to search by LOV Button

Using LOV button %Search for record and when click Ok then

FRM-40501 ORACLE error unable to reserve record for update or delete
ORA-00903 invalid table name

Maybe problem in Column Maping Properties but I dont know how to overcome

Any hint...

Which block is :search in?
Is that block based on a table?

Now SELECT * FROM DUAL; Replace by Table Name 'mast' and those Errors disappeared

Still problem in Column Maping Properties, when press Ok on LOV it replace the Current Cursor position

I want to jump on that row not Map on Current Cursor position

You might want to do it via LOV but LOVs aren't really designed for this job.
To use an LOV the LOV is going to have to be attached to a non-database item - it has to return a value for you to work with and that value has to go somewhere.
If you put it in a datablock item then forms will think you changed data when you didn't want to.

So the LOV needs to be attached to search and you should be able to put your when-button-pressed code in key-listval. You'll need to add code to call the LOV and then change the block that holds the queried data.

When-New-Form-instance

DECLARE
	CURSOR c1 IS
	SELECT * FROM Test_Table;
BEGIN
	Clear_Block(No_Validate);
	First_Record;
	FOR i IN c1
	LOOP
		:Block1.Code := i.Test_Code;
		:Block1.Name := i.Test_Name;
		Next_Record;
	END LOOP;
	First_Record;
END;

When-Button-Pressed Bring me to another Window/Canvas

Show_View('Canvas2');
Go_Item('Block2.Code');
DECLARE
	CURSOR c1 IS
	SELECT * FROM Test_Table;
BEGIN
	Clear_Block(No_Validate);
	First_Record;
	FOR i IN c1
	LOOP
		:Block2.Code := i.Test_Code; --Block 2
		:Block2.Name := i.Test_Name; --Block 2
		Next_Record;
	END LOOP;
	First_Record;
END;

Here I desined Modal Window Look Like LOV Where i search my result from 1000 result to 5, now from 5 i selected a result
Is it possible to hold my CURSOR_VALUE into a Variable or Global Variable and pass to below "EXIT WHEN :SYSTEM.CURSOR_VALUE = ???"
When-Button-Pressed

BEGIN
  Show_View('Canvas1');
  Go_Item('Block1.Code');
  First_Record;
  LOOP
    EXIT WHEN :SYSTEM.CURSOR_VALUE = ???????????;
    EXIT WHEN :SYSTEM.LAST_RECORD='TRUE';
    Next_Record;
  END LOOP;
END;

Last one is edited because that was not making any sense, Please Help me on this.

Begin
:Global.Val := :SYSTEM.CURSOR_VALUE;
Show_View('Canvas1');
Go_Item('Block1.Code');
LOOP
	EXIT WHEN :SYSTEM.CURSOR_VALUE = :Global.Val;
