Hi,

I try to call API namely ssfrfc which is provided by SAP and located in SAPGUI dir in my desktop. You also will have this API program if you installed SAPGUI. When calling this API using call function....destination 'SAP_SSFATGUI' via WebDynpro ABAP it giving me communication_error . However no problem when using normal ABAP. Below are the coding.

METHOD onactionact_exe .

DATA: ostr_output_data TYPE ssfparms-outtext,

ostr_output_data_l TYPE ssfparms-outtextlen,

crc TYPE ssfparms-ssfcrc,

lv_sysubrc type sysubrc.

• call C function 'SSFVERSION'

CALL FUNCTION 'SSFVERSION' DESTINATION 'SAP_SSFATGUI'

IMPORTING

ostroutputdata = ostr_output_data

ostroutputdatal = ostr_output_data_l

crc = crc

EXCEPTIONS

communication_failure = 1

system_failure = 2.

lv_sysubrc = sy-subrc.

• write:/ OSTR_OUTPUT_DATA,

• / OSTR_OUTPUT_DATA_L,

• / CRC.

Hi,

Try to wrap the RFC into a local function i.e., create a z-FM in local system and inside the FM call the RFC.

Let me know if that works.
