Help needed in Master Detail Form - 2 level of details

Question

Hi,
I have a form with 2 levels of Master Detail and a Find window
The Datablocks are
- Batch
- Headers
- Lines
- Manual datablock for Find Wndow
I have created relation between Bacthes and Headers with Batch Id
I have created relation between Headers and Lines using HeaderId.
The issue is that,
If I search with '%' in Batch block, by default it will show results in 'Headers' and 'Lines' block.but if i navigate to the next record in batch block , only Headers block shows results but Lines block does not show result.
If I search from Find window also, only Batch and Headers block shows results but Lines block will be empty.
In the 'Batch' block if I search with specific data , the screen shows results in 'Headers' and 'Lines' block.
Can you please help me solve it.
I have written a PRE-QUERY on Batches block to set where clause from Find window.
I have written a PRE-QUERY in Headers block to set where clause from Find window
Thanks,
Kamath.

Hi,
When you execute normal not by searching through ENTER_QUERY mode. Then data is coming in all blocks
- Yes. Once I go to the Form if I search using '%' in batch block or search for a particlaur record i Batch block, the results shows up in Headers and Lines block.
Ex: say there are 2 records in Batch block(A and B) and I search by %, by default i get 1 batth record (A) and corresponsding headers and lines
now when i use down arrow key in the batch block, second record(B) will be showed in batch block. relevant Headers block records will be shown but Lines block does not get queried.
Similarly if coem to the Form from search window then also, Batch and Header blcoks wil be shown but not Lines block
PREQUERY at Batch Level_*
V_WHERE := 'WHERE 1 = 1';
IF :XXYH_ICAN_CALC_WB_FIND.PERIOD IS NOT NULL THEN
     V_WHERE :=      V_WHERE || ' AND PERIOD = '''||:XXYH_ICAN_CALC_WB_FIND.PERIOD||'''';
END IF;               
IF :XXYH_ICAN_CALC_WB_FIND.BATCH_ID IS NOT NULL THEN
     V_WHERE :=      V_WHERE || ' AND BATCH_ID = '''||:XXYH_ICAN_CALC_WB_FIND.BATCH_ID||'''';
END IF;
IF      V_WHERE IS NOT NULL THEN
     set_block_property('XXYH_ICAN_WB_BATCHES',DEFAULT_WHERE,V_WHERE );                          
END IF;     
PRE-QUERY at Header Level_
IF :XXYH_ICAN_CALC_WB_FIND.BATCH_ID IS NOT NULL THEN
     V_WHERE :=      V_WHERE || ' AND BATCH_ID = '''||:XXYH_ICAN_CALC_WB_FIND.BATCH_ID||'''';
END IF;
IF      V_WHERE IS NOT NULL THEN
set_block_property('XXYH_ICAN_WB_TRX_HEADERS',DEFAULT_WHERE,V_WHERE );
END IF;
