Dynamic ALV control

[Former Member]

I have four containers in my final output.

TYPES: BEGIN OF GS_OUTTAB.

TYPES: CHECKBOX TYPE C. "field for checkbox

TYPES: CELLTAB TYPE LVC_T_STYL. "field to switch editability

INCLUDE STRUCTURE PA0001.

TYPES: END OF GS_OUTTAB.

Thats the final output table for the first container. How Can I do it dynamically for four different infotype tables. A field symbol for PA0001? Is that possible.

Please advice.

Hi,

1) Create fieldcatlog of your define fields.

2) Pass the fieldcatlog to this function module REUSE_ALV_FIELDCATALOG_MERGE and Name of table structure of infotype you want.

It create dynamic fieldcatlog of your pass structure infotype.

I have four containers in my final output.

A single container is enough, create the internal table dynamically and pass it.

This example might help you.

Please search in SCN , you will get lot of posts related to this( dynamic internal table )

 data:    wf_ref TYPE REF TO data,
     wf_line TYPE REF TO data.
   field-symbols:           <fs_tab> TYPE table,
              <fs_line> TYPE ANY.
  SELECT * FROM dd03l INTO TABLE i_dd03l WHERE tabname EQ wf_tab.
  IF sy-subrc EQ 0.
    SORT i_dd03l BY position ASCENDING.
    DELETE i_dd03l WHERE fieldname CP '.INCLU*'.
  ENDIF.

 LOOP AT i_dd03l ASSIGNING <fs_dd03l>.
    IF <fs_dd03l>-keyflag EQ abap_true.
      wa_cat-key = abap_true.
    ENDIF.
    wa_cat-fieldname = <fs_dd03l>-fieldname.
    wa_cat-col_pos = sy-tabix.
    wa_cat-inttype = <fs_dd03l>-inttype.
    wa_cat-datatype = <fs_dd03l>-datatype.
    wa_cat-intlen = <fs_dd03l>-intlen.
    wa_cat-seltext = <fs_dd03l>-fieldname.
    wa_cat-decimals = <fs_dd03l>-decimals.
    wa_cat-ref_field = <fs_dd03l>-fieldname.
    wa_cat-ref_table = wf_tab.
    APPEND wa_cat TO i_cat.
    CLEAR wa_cat.
 ENDLOOP.

You only need a few lines to create a dynamic internal table...

DATA: dataref TYPE REF TO data.

FIELD-SYMBOLS: <fs_tab> TYPE ANY TABLE.

CREATE DATA dataref TYPE STANDARD TABLE OF (wf_tab).

ASSIGN dataref->* TO <fs_tab>.
