Hi Raj,
Is there any possibility you can move to location heuristics, rather then running a network one, that one will be the easiest for you.or you can have different options like.
1) Deleting US receipts before US run.
2) Set SNP horizon in a way that short term receipts are not disturbed by SNP for US plants.
Check if any of the option is helpful in your case.
