EFG_PRINT : how to pass custom form parameter

Hi Experts,

We are using print work bench ( PWB ) to enhance new Talent Management form's. Standard forms are called by passing CP ( Central Person) & these execute fine & display content. We have created a Z Profile and Z-PDF form that we plan to call in standard way using FM EFG_PRINT.

To Z-PDF form interface we have added a new importing parameter IS_DISPLAY_FIELDS. Now how do i specify to the this Additional Parameter to EFG_PRINT.  EFG_PRINT does'nt seem to have any parameter where i can specify values for IS_DISPLAY_FIELDS

Thanks

Regards

Prashant
