SAP ABAP Getting the list of fields in the current layout using CL_SALV_TABLE
Getting the list of fields in the current layout using CL_SALV_TABLE
Hi Experts,
I am displaying the data available by using the class cl_salv_table.
I have been successful in displaying the table. But now I need to write a logic to download the table to the application server.
While downloading, I also need to consider the layout of the ALV selected. (The layout field is also provided in the selection screen and options are provided to run the program in background).
I am able to get the current layout of the ALV using CL_SALV_TABLE->GET_LAYOUT method (which will again be the value in the selection screen), but I couldnt find any method to find outthe fields available in current layout and the order of the fields.
Please help me finding out the same.
Thanks in advance,
Yuvaraj S

Read Former Member's sample ALV fieldcatalog - create for ANY table which use methods get_columns and get_aggregations to get information from cl_salv_table and then rebuild the "classical" field catalog with method cl_salv_controller_metadata=>get_lvc_fieldcatalog.Regards,

Yes, you can use they way Raymond mentioned. But: By far easier is the use of the columns object, i.e.
DATA:lo_columns TYPE REF TO cl_salv_columns_list,
lt_column_ref TYPE salv_t_column_ref.
FIELD-SYMBOLS
<column> TYPE LINE OF salv_t_column_ref.
• get columns object
lo_columns = mo_salv->get_columns( ).• get table of columns
lt_column_ref = lo_columns->get( ).LOOP AT lt_column_ref ASSIGNING <column>.In the loop, you may use all required methods to get characteristics of each column, the name is in <column>-columnname and the columns reference is in <column>-r_column->. I.e. <column>-r_column->get_decimals( ) gives numer of decimals of the column. The order of fields displayed is the order in lt_fields.

Hi,
I must have been more clear with my question.
I am have provided o_layout->set_save_restriction( if_salv_c_layout=>restrict_none ) option.This would allow me to save a Variant with any fields in any order.
cl_salv_controller_metadata=>get_lvc_fieldcatalog or mo_salv->get_columns( ) would give me the field catalogue for entire table. But I need to get the field catalogue for the variant that is chosen currently.I searched for classes but since I couldn't find any, I am using a classical FM 'LT_DBDATA_READ_FROM_LTDX'..
This FM gives me details of all the fields and their order for the currenr variant.
Is there any other class methods that I can use for this situation?
Thanks,
Yuvaraj S
