assuming you're trying to update the details for a certain subset of headers

try this..


UPDATE credit_detail
   SET itmprc = 2.59
 WHERE EXISTS
           (SELECT NULL
              FROM credit_header
             WHERE credit_header.customer = 26187
               AND credit_header.chain = 0
               AND credit_detail.item = 60200
               AND credit_header.cid = credit_detail.cid);
