dynamic Structure Creation !!

Former Member — Fri, 16 Dec 2005 08:49:21 GMT

hi all ,

I have two function Module with different structute with the same Table name parameter

Like in FM1 :

Tables : I_Tab Like Structure1

And Second FM2 Program2 :

Tables : I_Tab Like Structure2

And this two FM will call my Function module which i need to built with the same processing for both.

So, Can i create a dynamic structure based on the caller FM.

That is if FM1 Calls then I create I_Tab with Stru1

and if FM2 Calls then I create I_Tab with Stru2

Hope i m clear to present my problem

You can try to use this solution:

DATA: GT_FIELDCAT TYPE LVC_T_FCAT.

DATA: MY_TABLE TYPE REF TO DATA,

MY_WORKAREA TYPE REF TO DATA.

FIELD-SYMBOLS: <TABLE> TYPE TABLE,

<WA> TYPE ANY.

DATA: STRACTURE_NAME LIKE DD02L-TABNAME.

Create internal table

IF FM = FM1

STRACTURE_NAME = .....

ELSE.

STRACTURE_NAME = .....

ENDIF.

CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'

EXPORTING

I_STRUCTURE_NAME = STRUCTURE_NAME

I_CLIENT_NEVER_DISPLAY = 'X'

I_BYPASSING_BUFFER =

CHANGING

CT_FIELDCAT = GT_FIELDCAT

EXCEPTIONS

INCONSISTENT_INTERFACE = 1

PROGRAM_ERROR = 2

OTHERS = 3

IF SY-SUBRC <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

CALL METHOD CL_ALV_TABLE_CREATE=>CREATE_DYNAMIC_TABLE

EXPORTING

I_STYLE_TABLE =

IT_FIELDCATALOG = GT_FIELDCAT

IMPORTING

EP_TABLE = MY_TABLE

E_STYLE_FNAME =

EXCEPTIONS

GENERATE_SUBPOOL_DIR_FULL = 1

OTHERS = 2

IF SY-SUBRC <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

ASSIGN MY_TABLE->* TO <TABLE>.

Create work area

CREATE DATA MY_WORKAREA LIKE LINE OF <TABLE>.

ASSIGN MY_WORKAREA->* TO <WA>.

or this:

DATA: ITAB1 LIKE STANDARD TABLE OF <STRUCTURE1>,

ITAB2 LIKE STANDARD TABLE OF <STRUCTURE2>.

FIELD-SYMBOLS: <TABLE> TYPE TABLE.

IF FM = FM1

ASSIGN ITAB1 TO <TABLE>.

ELSE.

ASSIGN ITAB2 TO <TABLE>.

ENDIF.

hi thanks

But caller function module is passing the values to my function module .

so how to do that >

that is how to use that data from caller fm

Your fm should have a parameter table without reference, so it'll have the structure of the table transfered from caller.

Can you give me your code where you manage this calling?
