Upgrade scope of existing union all...

Using DB2 V9.7.500.702, Build Level S111017, PTF IP23287, Level IBM 1.6.0.

Is it possible to tweek the SQL call below with its multiple 'union alls' so that the retrievals from the 'DFN_CSH_REC_TRN_SQ' table which are trying to 'exclude' building a result if an 'R03' TRAN_CD is found in that table......will look for that 'R03' TRAN_CD even if it is 'preceded' in the table by an 'R02' or other value which is lower in row sequence than 'R03'. The SQL fails to satisfy existing needs now because 'R02' or 'R01' may precede the 'R03's in that table and thus those rows are 'accepted' and retrieved.....but the 'R03' presence should prevent that from happening.
