Hi, please help if anybody know joins involving ap_checks_stocks_all and ap_check_formats with ap_invoice_selection_criteria

Question

I am supposed to do a R12 upgrade/implementation in 2 days for a report which has a query as below, though it looks simple, it seems complicated or maybe I think it is  :
SELECT DECODE(aisc.status,
                  'BUILT','N',
                  'FORMATTING','N',
                  'QUICKCHECK','N',
                  'Y'),
           DECODE(aisc.status,
                  'QUICKCHECK','Y',
                  'N')
      FROM ap_invoice_selection_criteria aisc,
           ap_check_formats acf,
           ap_check_stocks acs,
       ap_bank_accounts ba,
       ap_bank_branches bb
     WHERE aisc.checkrun_name  = :P_PAYMENT_BATCH
       AND acs.check_stock_id  = aisc.check_stock_id
       AND acs.check_format_id = acf.check_format_id
       AND ba.bank_account_id = ACS.bank_account_id
       AND ba.bank_branch_id = bb.bank_branch_id;
But what I also do not understand is what is the use of ap_check_stocks and ap_check_formats in the above query
And also please let know if I can replace it with the following query or is it a totally wrong to do so and what shall miss out if i do so.
SELECT DECODE(aisc.status,
                  'BUILT','N',
                  'FORMATTING','N',
                  'QUICKCHECK','N',
                  'Y'),
           DECODE(aisc.status,
                  'QUICKCHECK','Y',
                  'N')
      FROM ap_invoice_selection_criteria aisc,
             apps.iby_ext_bank_accounts ba,
           apps.CE_BANK_BRANCHES_V bb
     WHERE aisc.checkrun_name  = :P_PAYMENT_BATCH
       AND ba.ext_bank_account_id = aisc.bank_account_id
       AND ba.branch_id = bb.branch_party_id;
New to these queries too. Sorry if there is a silly point I m asking.
Thanks a lot.

Hi,
as this issue is related to APPS better to post your query in the apps forum.
