Dynamic Field catalog

[Former Member]

Hello All,

I am creating an ALV using SLIS. The number of columns to be displayed in the ALV are not fixed they are determined using the function module dynamic_table_create. My problem is I want to create the field catalog for the ALV. How can I create the field catalog dynamically.

thanks,

Hi ucan do it this way..

For Eg:

DATA: COUNTER TYPE I,

LV_COUNTER TYPE CHAR2,

LV_FIELD TYPE CHAR10.

LOOP AT INT_BUKRS INTO WA_BUKRS.

COUNTER = COUNTER + 1.

LV_COUNTER = COUNTER.

CONCATENATE 'BUKRS' LV_COUNTER INTO LV_FIELD.

CONDENSE LV_FIELD.

IS_LVC_CAT-fieldname = LV_FIELD.

IS_LVC_CAT-SCRTEXT_L = WA_BUKRS.

APPEND IS_LVC_CAT TO IT_LVC_CAT.

IS_FIELDCAT-fieldname = LV_FIELD.

IS_FIELDCAT-OUTPUTLEN = 10.

IS_FIELDCAT-SELTEXT_L = WA_BUKRS.

APPEND IS_FIELDCAT TO IT_FIELDCAT.

ENDLOOP.

• create dynamic table:

• Create a new Table

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = IT_LVC_CAT

IMPORTING

ep_table = new_table.

Hope this helps..

There are lot of material in wiki explaining the same..

You can use the SALV technique to display your dynamic internal table as it doesn't require a field catalog

Refer to my response in this thread:

Use fm LVC_TRANSFER_TO_SLIS .

On input pass lvc fieldcatalog (which you used for table generation), on output receive slis one . Then pass your generated table and slis fieldcatalog to REUSE_ALV_GRID_DISPLAY .

hello ,

You can use the following code after populating your internaltable ,

LOOP AT IFLDCAT INTO WA_FLDCAT.

IF WA_FLDCAT-FIELDNAME = 'CURRENCY'.

WA_FLDCAT-col_pos = 0.

WA_FLDCAT-EDIT = 'X'.

WA_FLDCAT-seltext_m = 'Curr.of fare'.

WA_FLDCAT-seltext_s = 'Fare in currency'.

MODIFY IFLDCAT FROM WA_FLDCAT .

CLEAR WA_FLDCAT.

ENDIF.

ENDLOOP.

with regards ,
