SRM/External catalog in ECC Web Dynpro for ABAP

Question

Hi SRM experts!
Currently I'm developing new WB4A application in ECC and I faced one problem. Functionality will be let say light version of IW31 and same as in ERP transaction I would like to call catalog (external or SRM) and pass back selected materias to my WDA. Have anyone any idea how to do it, may be someone has a guide book?
Thanks in advance

Hi,
Have a look in the Function WSI_IMPORT_DATA where there is a section for WDA import:
importing Data via Webdynpro
    WHEN c_wdy.
      READ TABLE it_form_fields WITH KEY fieldname = '~XML_TYPE'
      INTO ls_its_context.
    we have an XML document, get it
      IF sy-subrc = 0.
        lv_xml_type = ls_its_context-fieldcont.
        LOOP AT it_form_fields WHERE fieldname <> '~xmlDocument'.
          DELETE it_form_fields.
        ENDLOOP.
        SORT it_form_fields BY fieldindex.
        LOOP AT it_form_fields.
          CONCATENATE lv_xml_document_b64 it_form_fields-fieldcont
          INTO lv_xml_document_b64.
        ENDLOOP.
        IF lv_xml_document_b64 IS INITIAL.
          RAISE import_error.
        ENDIF.
        CLEAR ls_its_context.
        lv_data_format = c_xml.
      ELSE.
      we have the HTML-version, get the complete fields
      longtext has been split up already on the java server
        lt_its_context[] = it_form_fields[].
        lv_data_format = c_html.
      ENDIF.
  ENDCASE.
Then the function BBP_WS_IMPORT_SC_DATA is the one used to interpret the data and map the OCI structures to Internal Structures.
There should be enough hints in this code to achieve your requirements or to just reuse a lot of the code here.
Please note these are SRM functions, so I am not sure if they would be available to you in ERP.
