you need where

var query = in salelist             group a.cust_ledger_entry_no g             g.sum( s => s.amount) > 0             select new { cust_ledger_entry_no = g.key, sumamount = g.sum( s => s.amount) }; 

---

i need result like, customers sum of amount greater 0 columns

if a customer , need select can use query:

var query = in salelist             group a.cust_ledger_entry_no g             g.sum( s => s.amount) > 0             customer in g  // flatten each group             select customer;
