Try using a sub select in order to get the most recent sequence number, like below:

SELECT DISTINCT(ca.cust_acct_id)                 
FROM cwo_work_order_acct ca              
INNER JOIN
(
SELECT 
    act.organization_id,
    act.wkstn_id,
    act.business_date,
    act.rtl_loc_id,
    act.rtrans_lineitm_seq,
    max(act.trans_seq) trans_seq --Get the most recent seq number
  FROM cat_cust_item_acct_activity act                
  GROUP BY
        act.organization_id,
        act.wkstn_id,
        act.business_date,
        act.rtl_loc_id,
        act.rtrans_lineitm_seq        
  ) as acty
  ON  ca.organization_id = acty.organization_id                     
  AND ca.cust_acct_id = acty.cust_acct_id                     
  AND ca.cust_acct_code = acty.cust_acct_code

INNER JOIN cwo_work_order_line_item cli                         
  ON  acty.organization_id = cli.organization_id                         
  AND acty.wkstn_id = cli.wkstn_id                         
  AND acty.trans_seq = cli.trans_seq                         
  AND acty.business_date = cli.business_date                         
  AND acty.rtl_loc_id = cli.rtl_loc_id                         
  AND acty.rtrans_lineitm_seq = cli.rtrans_lineitm_seq              
  AND cli.price_status_enum ='ESTIMATE'
