Query forms based on detail block

Question

My question is pretty simple: Is it possible to query a form (Forms [32 Bit] Version 6.0.8.11.3) based on a detail block? Let me explain my problem! I have a table called REQUISITION and of its field is STATUS_CODE. Then I have another table called STATUS that have the following fields: CODE, NAME, DESCRIPTION, PHASE, etc. The join condition between REQUISTION and STATUS is REQUISITION.STATUS_CODE = STATUS.CODE. On my form, all of the fields come from table REQUISITION but the problem is that we have over 30 different status and my user can't remember their names and phase. So I inserted two display fields on the forms and wrote a post-query trigger to populate the field with their corresponding names and phases. But now my end user are complaining that the fields don't allow queries to be performed which prevents them to use a query to know all requisitions that are on phase "Procurement" which corresponds to four different status_code. So I though in inserting the fields PHASE and DESCRIPTION into table REQUISITION and write a trigger that would populate those field every time the STATUS change but that would cause a problem when lets say STATUS 01 is part of PHASE "Procurement" then comes next week the company decides that is not longer part of phase "Procurement" but now it is part of PHASE "Purchasing" they would go the form based on table STATUS and change the field PHASE of the corresponding STATUS that they want. But now I have this data on another table holding information that is no longer valid. Sure I could write another trigger to change field REQUISITION.STATUS_PHASE whenever there is a change on STATUS.PHASE but wouldn't that be too much bookkeeping? Would be so much easier if I could query my forms based on the detail block (this case table STATUS and master block table REQUISITION)?
thanks so much in advance for any thought! Btw, I am open to other suggestions too!!!!!

Answer 1

if I understood you correctly, you can do this manually. what I mean is,
when the end user picks phase "Purchasing", you can change the where clause on the master block and execute the query to get the desired results
e.g.
v_cod varchar2(200) := 'STATUS_CODE in (select code from status where phase = ''Purchasing'')';
begin
set_block_property(requisition_blk,default_where,v_cod);
execute_query;ofcourse you have to change "Purchasing" in the previous code to the item that holds the user inputs
hope this is helpful
