Usage error while generating spool for adobe forms

Question

I need to create a function module which would be called from a BRF. The function module must generate an adobe form and sent to the spool.
I get usage error at the call form function module level. could someone suggest if anything is missing in the below code.
""Local Interface:
*" IMPORTING
*" REFERENCE(I_FORM_NAME) TYPE FPNAME
*" REFERENCE(I_BP_DETAILS) TYPE ZRP_STRU_RTRN_BP_DETAILS
*" REFERENCE(I_AMT_DETAILS) TYPE ZRP_STRU_RTRN_AMT_DETAILS
*" EXPORTING
*" REFERENCE(E_RETURN) TYPE BAPIRET2_T

ga_outputparams TYPE sfpoutputparams,
gs_docparams TYPE sfpdocparams,

Get the Form function module name
CALL FUNCTION 'FP_FUNCTION_MODULE_NAME'
EXPORTING
i_name = i_form_name
IMPORTING
e_funcname = gv_fm_name
E_INTERFACE_TYPE =
