problem in using function module parameters in abap program

[Former Member]

i want to use the coding present in on one of the function module 'AS_API_INFOSTRUC_FIND' i got the problem using the function module parameters in my abap program.

these are the parameters inside fm

""Lokale Schnittstelle:

*" IMPORTING

*" VALUE(I_FIELDCAT) TYPE AIND_FCAT

*" VALUE(I_FIELDS) TYPE TABLE OPTIONAL

*" VALUE(I_OBLIGATORY_FIELDS) TYPE TABLE OPTIONAL

*" EXPORTING

*" VALUE(E_INFOSTRUC) TYPE AIND_DESC

*" REFERENCE(E_ALL_FIELDS) TYPE TABLE

*" REFERENCE(E_MATCHING_FIELDS) TYPE TABLE

*" EXCEPTIONS

*" NO_INFOSTRUC_FOUND

i want to declare E_ALL_FIELDS parameter in my abap program,

i have declared as

data: E_ALL_FIELDS TYPE TABLE.

but the system throws error that

'type of field 'TABLE' is generic .no table line has been specified'.

i want to use it in my abap program how can i declare in my abap program .

You have to declare the table using any specific type.

The type table in the FM is generic so you can pass any type you need.

For instance:

TYPES: BEGIN OF ty_fields,
         fieldname LIKE dfies-fieldname,
       END OF ty_fields,



TYPES: TY_T_GLU1              LIKE GLU1                     OCCURS 0,
       ty_t_fields            type ty_fields                occurs 0.



  DATA: lt_info_struct_fields TYPE ty_t_fields WITH HEADER LINE,
        lt_matching_fields    TYPE ty_t_fields WITH HEADER LINE.


    CALL FUNCTION 'AS_API_INFOSTRUC_FIND'
         EXPORTING
              i_fieldcat         = ft_fieldcat-fieldcat
              i_fields           = ft_fields_filled[]
         IMPORTING
              e_infostruc        = lv_info_struct_name
              e_all_fields       = lt_info_struct_fields[]
              e_matching_fields  = lt_matching_fields[]
         EXCEPTIONS
              no_infostruc_found = 1.
