You can try something like this;

SELECT NVL(CU.Name,"") AS CustName, NVL(LD.Name,"") AS LedgerName, IIF(EMPTY(IN.Cust_code,"Cash Sale","") AS CashSale, IN.* ;
  FROM Inventory IN ;
LEFT JOIN Customer CU ON IN.Cust_Code = CU.Cust_Code ;
LEFT JOIN Ledger LD ON IN.Cust_Code = LD.Cust_Code ;
INTO CURSOR MyResult

This is off the top of my head and has not been tested so you need to some debugging.
