Retrieve IDoc Segment Format

[Former Member]

I am using the SAP function IDOC_SEGMENT_STRUCTURE_READ to retrieve the structure of an IDoc segment. This function returns a table SEGMENT_STRUCT of type LEDID_T_SEGMENT_STRUCT.

When I call this function from my ABAP function, I am using the following definition for the table I am sending to IDOC_SEGMENT_STRUCTURE_READ:

Data: lt_segstru type table of LEDID_T_SEGMENT_STRUCT.

I am using the same type in my internal function as is used in the SAP function, but when I try to activate my function, I am receiving the following error:

The type "LEDID_T_SEGMENT_STRUCT" is unknown.	

I see that LEDID_T_SEGMENT_STRUCT points to the type group of LEDID. How do I write my table definition in my calling function to match the format of the table returned in IDOC_SEGMENT_STRUCTURE_READ?

Hi!

you can try with this program:

don't forget to include the "TYPE-POOLS ledid." line at the begining, this is the reason why you are receiving the error message.

REPORT ztestdpo2 .

TYPE-POOLS ledid.

PARAMETERS: p_segtyp LIKE edisegmhd-segtyp.

DATA t_segment_struct TYPE ledid_t_segment_struct.

DATA wa_segment_struct LIKE LINE OF t_segment_struct.

CALL FUNCTION 'IDOC_SEGMENT_STRUCTURE_READ'

EXPORTING

• RELEASE = SY-SAPRL

segtyp = p_segtyp

• VERSION = '3'

TABLES

segment_struct = t_segment_struct

EXCEPTIONS

segment_unknown = 1

segment_structure_unknown = 2

segment_not_in_release = 3

OTHERS = 4

.

IF sy-subrc <> 0.

MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno

WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.

ENDIF.

LOOP AT t_segment_struct INTO wa_segment_struct.

WRITE:/ wa_segment_struct.

ENDLOOP.

In your TOP include, add the following statement.

TYPE-POOLS LEDID.
