L_TO_CONFIRM - Print issue in SP02

Hi,

I am developing Neptune mobile application and in that I am using L_TO_CONFIRM function module to confirm the transfer order. In standard sap it is generating Spool request with Completed(Green) status. Where as in my application I am using the same function module to confirm transfer order but I am getting Spool request with Error(Red) status.

Note: I observed that there is no print parameters in L_TO_CONFIRM function module.

Regards,

Haritha.
