[Former Member]

Hi All,

Any info on how to create a dynamic internal table along with columns(fields) also to be created dynamically.

My requirement is ..On the selection screen I enter the number of fields to be in the internal table which gets created dynamically.

I had gone thru some posts on dynamic table creation,but could'nt find any on the dynamic field creation.

Any suggestions pls?

Thanks

*----------------------------------------------------------------------*
*   Form P_MODIFY_HEADER.                                              *

  data : is_fieldcatalog type lvc_s_fcat ,
         v_count(2)      type n ,
         v_date          type d ,
         v_buff(30).



* Update the fieldcatalog.
  loop at it_fieldcatalog into is_fieldcatalog.
    check is_fieldcatalog-fieldname+0(3) eq 'ABS' or
          is_fieldcatalog-fieldname+0(3) eq 'VAL' .
    move : is_fieldcatalog-fieldname+3(2) to v_count ,
           p_perb2+5(2)                   to v_date+4(2) ,

Hi Fred,

The requirement is like this...

I enter 110 or 200 on the selection screen and the internal table as below to be created dynamically.

Data: Begin of it_itaboccurs 0,

FIELD1(19),

FIELD2(19),

FIELD3(19),

FIELD4(19),

FIELD5(19),

FIELD6(19),

FIELD7(19),

FIELD8(19),

FIELD9(19),

and so on.... till field110 or may be FIELD9200,

end of it_itab.

Hope you are now clear of my requirement.

Thanks

It's the code I give you. My code is to change the number of column depend of the number of month the user select.

You just have to create a good table it_fieldcatalog, with the 200 column dynamicly (depend of the number enter in your selection-screen).
