ASSIGN COMPONENT from a table to a dynamic table

[Former Member]

every body,

     there is a very interesting thing,i didn't use before.

     in a programe,i want to transfer data from a internal table to a dynamic table,and the table tb_data may be diffrent every time,so i coded follow:

CALL METHOD CL_ALV_TABLE_CREATE=>CREATE_DYNAMIC_TABLE
     EXPORTING
       IT_FIELDCATALOG = IT_FLDCAT
     IMPORTING
       EP_TABLE        = DREF.
 
   ASSIGN DREF->* TO <GT_DYN_TABLE>.
 
   ASSIGN COMPONENT 0 OF STRUCTURE TB_DATA[] TO <GT_DYN_TABLE>.

not used work area and assign filed one by one,the <GT_DYN_TABLE> get structure and has all data from TB_DATA.but the <GT_DYN_TABLE> is diffrent with DREF now.

ps,i don't want the table <GT_DYN_TABLE>  has the same fileds with tb_data,maybe one field more,is there any solution?

Hi,

first of all, the answer is yes.

Now for your code-sample. Upto ASSIGN DREF->* TO <GT_DYN_TABLE> everything is fine.

With the next Statement however, you messed it up..

Provided you are on NW 7.4 or later, you could just use

MOVE_CORRESPONDING TB_DATA[] TO <GT_DYN_TABLE>.

BTW. does your TB_DATA really have a headerline? And if so, to what purpose?

Otherwise the brackets [] aren't necessary.

On lower Releases, you'll need at least another set of field-symbols, one for each table.

Then, you can just

LOOP A TB_DATA ASSIGNING <FS1>.

APPEND INITIAL LINE TO <GT_DYN_TABLE> ASSIGNING <FS2>.

MOVE-CORRESPONDING <FS1> TO <FS2>.

ENDLOOP.

Or, in case you really have a Header line use:

LOOP AT TB_DATA INTO TB_DATA.

APPEND INITIAL LINE TO <GT_DYN_TABLE> ASSIGNING <FS2>.

MOVE-CORRESPONDING TB_DATA TO <GT_DYN_TABLE>.

ENDLOOP.

That should do the trick.

hi,Jörg

thank you for your response and i will try your suggest later

and the code is a part of a form,because of the tb_data is not static, so i didn't declare the type,  like this

FORM ASSIGNDATATODYNTABLE TABLES TB_DATA.

before the form,there is no header line.
