I'm working in a sem-bps project and I have a problem with an exit function, because
I need the function module to read the value of a characteristic's attribute.
I read the standard function module UPF_VARIABLE_USER_EXIT_ATTR: it retrieves the attribute value through the import parameters ITO_ATTR TYPE UPC_YTO_ATTR.
I put this attribute on my exit function but when I check the content of the attribute its always empty. Do you know how I can transmit the parameter from the exit planning function to the function module?
Any input is appreciated, thanks Andrea
