The reason why 'NonValidatedWebExpense' is set

Hi,

There is a mention in this Note as follows.

Explain the Meanings of SOURCE and WORKFLOW_APPROVED_FLAG Column values in Internet Expenses (Doc ID 107849.1)

>SOURCE     'NonValidatedWebExpense'

>Expense report transaction has been inserted into the expense report transaction tables but have not passed the Payables Validation Function in the Server Side Validation Process of the >Expense Report Workflow process.

The phenomenon that NonValidatedWebExpense was set was generated.

I ran following datafix, and the problem was settled.

UPDATE AP_EXPENSE_REPORT_HEADERS_ALL

SET SOURCE='WebExpense',

LAST_UPDATE_DATE = SYSDATE

WHERE REPORT_HEADER_ID = <REPORT_HEADER_ID>;

Question:

What does the Payables Validation Function in the Server Side Validation Process mean?
