ALV Column Text and Color won't change

 原文  2018-02-07 10:50:12  9   2    abap/ display/ alv

Question

I got a SAP ALV problem. I want to change the text and the color of a column. It works if I call the column directly ('BONUS') but when I use it within a DO-clause and concatenate the name of the column it won't work for some reason. Though the column is found and the attributes are changed, at least this is what I see in while debugging.

I hope someone can help me out here.

The following is a part of my coding where the attributes should be changed.

        Data: Count Type i.
  DATA: h_fieldname TYPE char30.
  DATA: col_s         TYPE scrtext_s.

  DATA: col_m         TYPE scrtext_m.

  DATA: col_l         TYPE scrtext_l.

  DATA: colname(30) TYPE c.

DATA: lr_functions TYPE REF TO cl_salv_functions_list.

 DATA: gr_columns    TYPE REF TO cl_salv_columns_table.

 DATA: gr_column     TYPE REF TO cl_salv_column_table.

DATA: alv TYPE REF TO cl_salv_table.

  lv_color_red-col = 7.
  lv_color_red-int = 1.
  lv_color_red-inv = 0.

  lv_color_blue-col = 4.
  lv_color_blue-int = 1.
  lv_color_blue-inv = 0.

  lv_color_green-col = 5.
  lv_color_green-int = 1.
  lv_color_green-inv = 0.
            DO gv_row_count TIMES.

          ADD 1 TO count.
          new = count.

          CLEAR: h_fieldname, colname.
          CONCATENATE 'JAHR' new 'P' INTO h_fieldname.
          CONCATENATE 'Jahr' new INTO colname.
          col_s = colname.
          col_m = colname.
          col_l = colname.
          gr_column ?= gr_columns->get_column( h_fieldname ).
          gr_column->set_short_text( col_s ).
          gr_column->set_medium_text( col_m ).
          gr_column->set_long_text( col_l ).
          gr_column->set_color( lv_color_blue ).

          CLEAR: h_fieldname, colname.
          CONCATENATE 'JAHR' new 'W' INTO h_fieldname.
          CONCATENATE 'Jahr' new INTO colname.
          col_s = colname.
          col_m = colname.
          col_l = colname.
          gr_column ?= gr_columns->get_column( h_fieldname ).
          gr_column->set_short_text( col_s ).
          gr_column->set_medium_text( col_m ).
          gr_column->set_long_text( col_l ).
        ENDDO.

I'm posting the code of both methods. The first one is building a fieldcatalog an creating a global table so the fieldcatalog could be used in the second method. This one should fill the fieldcatalog, configure the ALV (like column texts and colors) and display the result.

EDIT: Here are also the attributes etc. used inside the methods:
  data GT_DATATAB type ref to DATA .
  class ZCL_BONUS_PROCESSING definition load .

Well... you did not specify the type of the variable new but I will assume it is STRING . If it is then making such an assignment

new = count.

will not get rid of the space at the end of the count variable.

This simple program shows it.

REPORT ZZZ.

DATA: gv_row_count TYPE i VALUE 30.
DATA: fieldname TYPE char30.
DATA: new TYPE string.

START-OF-SELECTION.
   new = gv_row_count.
   CONCATENATE 'JAHR' new 'P' INTO fieldname.
   WRITE fieldname.

The output is JAHR30 P and not JAHR30P .

To work around it you can put the following statement after the CONCATENATE one.

CONDENSE h_fieldname NO-GAPS.

or even neater just use string templates instead of concatenating then you will not need the variable new .

h_fieldname = |JAHR{ count }P|.

If it works for one column, there's no reason that it doesn't with another one.

Do as usual to troubleshoot your code. Make sure that the column name is well written, and is the name of an existing column in the ALV table.
