Dynamic table for RFC function

Former Member — Thu, 20 Jul 2006 08:24:52 GMT

Hello,

Currently I am building a function group that retrieves information from a local database and a remote database. For the remote database I call a RFC function with the DESTINATION parameter. Now I would like to use a ANY TABLE for the TABLES parameter since the structure of that parameter does not exist in our system:

FIELD-SYMBOLS: <lit_table> TYPE ANY TABLE.

CALL FUNCTION 'BAPI_ZGETAGRDET'

DESTINATION 'XYZCLNT160'

EXPORTING

iv_datum = pa_date

iv_gpart = '1'

TABLES

et_table = <lit_table>.

This gives the error that its not ASSIGNED yet, is it even possible to call a function like this? Or do I need to copy the structure van the remote system to the local system and declare it staticly.

Any help is welcome and I'll reward point ofcourse.

Hi ,

If your FM is RFC enabled you can't declare a generic type. that is the problem when you try to use the FM and try to pass a dynamic table name to get the data from the remote system.

Hope this helps.

Hi,

Check these FM 's: RFC_READ_TABLE

RFC_GET_TABLE_ENTRIES

i think these will work for your requirement.

I have done it:

FIELD-SYMBOLS: <lwa_tabname> TYPE rfc_fields,

<lit_aanstelling> TYPE table.

DATA: lit_nametab TYPE TABLE OF rfc_fields,

lob_data TYPE REF TO data,

lit_fieldcat TYPE lvc_t_fcat,

lwa_fieldcat TYPE lvc_s_fcat.

CALL FUNCTION 'RFC_GET_STRUCTURE_DEFINITION'

DESTINATION 'N01CLNT160'

EXPORTING

tabname = 'ZCS_INTERM_AGR_DET_AANST'

TABLES

fields = lit_nametab

EXCEPTIONS

table_not_active = 1

OTHERS = 2.

IF sy-subrc <> 0.

ENDIF.

LOOP AT lit_nametab ASSIGNING <lwa_tabname>.

MOVE <lwa_tabname>-fieldname TO lwa_fieldcat-fieldname.

MOVE <lwa_tabname>-exid TO lwa_fieldcat-inttype.

MOVE <lwa_tabname>-intlength TO lwa_fieldcat-outputlen.

APPEND lwa_fieldcat TO lit_fieldcat.

ENDLOOP.

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = lit_fieldcat

IMPORTING

ep_table = lob_data.

ASSIGN lob_data->* TO <lit_aanstelling>.

It doesn't seem efficient copy data from table1 to table2 but it works...
