Dear Experts,
I am trying to call a FM in my code, but somehow I am getting the following error .Please help !
My code is :
DATA :  VENDOR_NO TYPE WSRS_SHVDST_RES-VENDOR_NO,
        PE_LFA2 TYPE LFA1,
        PE_ADDR2 TYPE BAPIADDR1,
        PE_ADRPRT2 TYPE WISO_ADRPRT,
        PE_RETURN2 TYPE WSRS_RETURN,
        PE_LFM2 TYPE LFM1,
        PE_LFB2 TYPE LFB1.
  DATA:
    node_vendor                         TYPE REF TO if_wd_context_node,
    elem_vendor                         TYPE REF TO if_wd_context_element,
    stru_vendor                         TYPE if_vendor_view=>element_vendor ,
    item_vendorinp                      LIKE stru_vendor-vendorinp.
navigate from <CONTEXT> to <VENDOR> via lead selection
  node_vendor = wd_context->get_child_node( name = if_vendor_view=>wdctx_vendor ).
get element via lead selection
  elem_vendor = node_vendor->get_element(  ).
get single attribute
  elem_vendor->get_attribute(
    EXPORTING
      name =  `VENDORINP`
    IMPORTING
      value = item_vendorinp ).
VENDOR_NO = item_vendorinp.
CALL FUNCTION 'WSRS_O_VENDOR_GET_DETAIL'
EXPORTING
PE_LFA1 = PE_LFA2
PE_ADDR1 = PE_ADDR2
PE_ADRPRT = PE_ADRPRT2
PE_RETURN =PE_RETURN2
PE_LFM1 = PE_LFM2
PE_LFB1 = PE_LFB2
IMPORTING
PI_VENDOR_NO = VENDOR_NO.
My Error is :

Hi,
I will ask this way, from where did you get list of parameters for this FM? Try using pattern to call this FM, than you will be proposed with correct interface.
EDIT:
After checking it in system you should switch IMPORTING and EXPORTING
CALL FUNCTION 'WSRS_O_VENDOR_GET_DETAIL'
  EXPORTING
    PI_VENDOR_NO             = '99'
*   PI_ACCEPT_NOTFOUND       =
*   PI_PURCH_ORG             =
*   PI_COMP_CODE             =
IMPORTING
   PE_LFA1                  = lv
*   PE_ADDR1                 =
*   PE_ADRPRT                =
*   PE_RETURN                =
*   PE_LFM1                  =
*   PE_LFB1                  =
