Update Stragedy for a lookup not cached

[gwright2005]

I am using Informatica 7.1, I have disabled the lookup cache (cannot use dynamic cache all conditions are not equal). Example the condition is looking for a update flag from the target table as a 'N'. My update stragedy is changing this flag to 'Y'. I have multiple input records and should update the target only once, but when I am in debug, it updates multiple times. I changed the workflow to not cache the lookup and the commit type is target and 1 row.
