How to include XPRA into transport request by code?

Hey experts,

is there some FM with which I can include a XPRA into transport request by code?

I usually use the following FM to include objects into TR, but it does not work for XPRA.

CALL FUNCTION 'RS_TOOL_ACCESS'

     EXPORTING

       operation           = 'TRANSPORT'

     TABLES

       objlist             = lt_objlist

     CHANGING

       p_request           = lg_request

     EXCEPTIONS

       invalid_object_type = 01

       not_executed        = 02

OTHERS              = 03.

Thank you.

Best regards,
Robert
