Hi Ashish,
we thought about it, however the region for both plants is Tokyo so that won't work, is there another parameter that we can look at.
I like Andrea's suggestion, just need to figure out the unique parameter and the way that parameter at item level will be auto filled (we want the user not to bother about this and would like to use a user exit to fill that parameter).
Can we create a key combination for Country/plant/ material/ customer tax classification & material tax classification
any thoughts
