title: Multiple text lines below report selection-screen parameters based on table entries
body: <p>Before executing my report I want to display the folders below the selection screen.<br>
  The folder names are stored inside a table.<br>
  Since I don't know how many entries the table has beforehand, this needs to be dynamic - not hardcoded.  </p>
  
  <p>This is what I've done so far:</p>
  
  <pre><code>DATA: lt_directories TYPE string_table.
  DATA: lv_folders_txt TYPE string.
  
  "Report description with test-checkbox
  SELECTION-SCREEN BEGIN OF BLOCK b11 WITH FRAME TITLE title.
  PARAMETERS: pa_test TYPE c AS CHECKBOX DEFAULT abap_true.
  SELECTION-SCREEN COMMENT /1(20) folders.
  SELECTION-SCREEN END OF BLOCK b11.
  
  INITIALIZATION.
    lt_directories = VALUE string_table( ( `FOLDER1` ) ( `FOLDER2` ) ( `FOLDER3` ) ( `FOLDER4` ) ).
    title = 'This program imports data from the listed folders'.
  
  AT SELECTION-SCREEN OUTPUT.
    LOOP AT lt_directories ASSIGNING FIELD-SYMBOL(&lt;directory&gt;).
      "TODO: this has to be changed!
      lv_folders_txt = lv_folders_txt &amp;&amp; &lt;directory&gt;.
    ENDLOOP.
    folders = lv_folders_txt.
  </code></pre>
  
  <p>This is how the result looks like:
  <a href="https://i.stack.imgur.com/69Wrx.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/69Wrx.png" alt="IST-Zustand"></a></p>
  
  <p>And this is an example of how I want it to look like:<br>
  <a href="https://i.stack.imgur.com/rQsb7.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/rQsb7.png" alt="SOLL_Zustand"></a></p>
  
  <p>Does someone know an easy way to do this?</p>
