Buck, You're right about not confusing multi-format with Joined. However, he just might be doing a join. Consider this, in a single physical with multi formats you do not need to replicate data 01-customer master 02-customer transaction 01cust#1 02bought some stuff 02bought more stuff 01cust#2 02bought some stuff 02bought more stuff But to break this out into different physical's so that you can externalize it, not duplicate customer# into each of the 02 records, and still read them in the proper sequence, can be done how? Either way, multiformat, or join, will require some duplication, to get it into the right order upon externalization, right? Oh well, in that case you may be right. He could use a multiformat, he'd just have the duplicated data also. Rob Berendt -- Group Dekko Services, LLC Dept 01.073 PO Box 2000 Dock 108 6928N 400E Kendallville, IN 46755 http://www.dekko.com
