hi mvrnk,
Dynamic Lookups r used with the target loads ..
When a Dynamic LKP is used in ur mappin with any target
a NEWLOOKUPROW port will b automatically created in the Dynamic LKP,
based on the NEWLOOKUPROW value u can insert/ reject the records..
if the NEWLOOKUPROW =1 ...means the row is a new row
NEWLOOKUPROW =0...means the row is an existing row..
hope u got it..
