Changing the Invoice numbering system for Withholding Tax Invoices

 Hi All,

We have a requirement of changing the numbering system of Withholding tax invoices created by system in Payables.

The default numbering created by system for withholding tax invoice as follows,

Withholding Tax - <invoice_id of the original standard invoice> - <distribution line number for the AWT line>

(example : Withholding Tax - 10239 - 3),

requirement is to remove the literal 'Withholding Tax' from the withholding tax numbering, 

and to have the withholding tax invoice number as 10239 - 3.

Any pointers or guidance would be helpful.

We are implementing R12.1.3.

Regards,

Subramanyam.
