Dynamic FM call using Structures and Tables

Hi All,

I am trying to call dynamic FMs. I am getting null object reference dump although I am passing respective data references.

I referred below links but couldn't help me to fix the issue:

ABAP Keyword Documentation

I assume that either value or data_ref column will have object references based on kind.

Dump :

Runtime Errors - DATREF_NOT_ASSIGNED

Except. - CX_SY_DYN_CALL_PARAM_MISSING

Please see the attachment.

Code:

lt_import[] = ls_details-import[].

lt_export[] = ls_details-export[].

lt_change[] = ls_details-change[].

lt_tables[] = ls_details-tables[].

lt_except[] = ls_details-except[].

lt_paratx[] = ls_details-paramtext[].

* Import Parameters

LOOP AT lt_import INTO ls_import WHERE optional = space.

ls_ptab-name = ls_import-parameter.

ls_ptab-kind = abap_func_importing.

IF ls_import-structure IS NOT INITIAL .

CREATE DATA lfs_dref TYPE (ls_import-structure).

ls_ptab-value = lfs_dref. "set data type

ENDIF.

INSERT ls_ptab INTO TABLE lt_ptab.

CLEAR:lfs_dref,ls_ptab, ls_import.

ENDLOOP.

* Export Parameters

LOOP AT lt_export INTO ls_export WHERE optional = space .

ls_ptab-name = ls_export-parameter.

ls_ptab-kind = abap_func_exporting.

IF ls_export-structure IS NOT INITIAL.

CREATE DATA lfs_dref TYPE (ls_export-structure).

ls_ptab-value = lfs_dref. "set data type

ls_ptab-tables_wa = lfs_dref.

ENDIF.

INSERT ls_ptab INTO TABLE lt_ptab.

CLEAR:ls_ptab, ls_export.

ENDLOOP.

* Changing Parameters

LOOP AT lt_change INTO ls_change WHERE optional = space..

ls_ptab-name = ls_change-parameter.

ls_ptab-kind = abap_func_changing.

IF ls_change-structure IS NOT INITIAL.

CREATE DATA lfs_dref TYPE (ls_change-structure).

ls_ptab-value = lfs_dref. "set data type

ENDIF.

INSERT ls_ptab INTO TABLE lt_ptab.

CLEAR:ls_ptab, ls_change.

ENDLOOP.

* Tables

LOOP AT lt_tables INTO ls_tables WHERE optional = space..

ls_ptab-name = ls_tables-parameter.

ls_ptab-kind = abap_func_tables.

IF ls_tables-structure IS NOT INITIAL.

CREATE DATA lfs_dref TYPE (ls_tables-structure).

ls_ptab-tables_wa = lfs_dref.

ENDIF.

INSERT ls_ptab INTO TABLE lt_ptab.

CLEAR:ls_ptab, ls_change.

ENDLOOP.

* Exceptions

LOOP AT lt_except INTO ls_except.

ls_etab-name = ls_except-parameter.

ls_etab-value = sy-tabix.

INSERT ls_etab INTO TABLE lt_etab.

CLEAR ls_etab..

ENDLOOP.

* Call Dynamic FM name to chck for runtime exceptions

CALL FUNCTION lv_fm_name

PARAMETER-TABLE

lt_ptab

EXCEPTION-TABLE

lt_etab.

CLEAR ls_stxfadm.

ENDLOOP.

Issue resolved.

Signature of FM was fetched using class CL_FB_FUNCTION_UTILITY=>METH_GET_INTERFACE.

Here Importing parameters in FM definition will act as Exporting parameters while passing signature to dynamic FM using PARAMETER-TABLE and vice-versa.

So ls_ptab-kind = abap_func_importing is changed to ls_ptab-kind = abap_func_exporting in First loop.

and ls_ptab-kind = abap_func_exporting is changed to ls_ptab-kind = abap_func_importing in second loop.
