We can override the lookup query for a relational lookup.
We can enter the entire override, or we can generate and
edit the default SQL statement.
Override the lookup query in the following circumstances:
1.Override the ORDER BY statement
2.A lookup table name or column names contains a reserved
word
3.Use mapping parameters and variables
4.A lookup column name contains a slash (/) character
5.Add a WHERE statement

Hi, I saw one mapping implemented by my seniors . In Expression transformation they implemented following logic. That is iif(is_date(in_UC_DATINV,'YYYYMMDD'),to_date(in_UC_DATINV,'Y YYYMMDD'),'Inventory Date is either invalid or null') Inventory_Date is validated only for is_date() But not validated for notisnull() . But error says “ either invalid or null “ why? Whether is_date() also check for not isnull() ? or in this logic something is different ? Please answer me . Advance thanks
