Missing tep_get_products_staff_price definition

[lead_pipes]

Hi,

 

I've been asked to located the cause of an error (I snipped out filename path):

"Call to undefined function: tep_get_products_staff_price() in product_info.php"

 

I can't find any files on the site containing that function definition.

Does anyone know where it's supposed to be and and from what module or contribution if any?

 

Thanks in advance for any clue.
