How To Hide Columns In Table Control

In this tutorial we will explain how to hide a column in a table control use in a Dynpro screen.

As example, we will hide a column in the table control ‘TC_DLSAM’ (used in the MRP transaction MD06).

Step 1:

In the flow logic of the screen where the table control is used, we will have to call a module in the screen PBO (Process Before Output) which will contains the appropriate code logic to hide the column.

Code to call the module ‘F_HIDE_COLUMN’:

*----------------------
PROCESS BEFORE OUTPUT.
*----------------------

* Some Codes…

 

* Calling the module which will hide the column.

  MODULE f_hide_columns.

Step 2:

The following code will hide the column ‘MRP Date’ from the table control ‘TC_DLSAM’.

 

Code:

*----------------------------------------------------------------------*
* Hiding the column \'MRP Date\' in the table control \'TC_DLSAM\' in      *
* screen 602 of transaction MD06.                                      *
*----------------------------------------------------------------------*
MODULE f_hide_column OUTPUT.
*----------------------------------------------------------------------*
* Other Declarations may be needed:
*  CONTROLS: tc_dlsam TYPE TABLEVIEW USING SCREEN 602.
*  TYPE-POOL CXTAB .
*  TYPES CXTAB_COLUMN type scxtab_column.
  
* Types:
  DATA:
    lst_cols TYPE cxtab_column.

* Constants:
  CONSTANTS:
    lc_column_mrp_date TYPE char10 VALUE \'MDKE-DSDAT\'.

* We will have to loop at the standard table control \'TC_DLSAM\' 
* deep structure \'COLS\' and we will modify the display attribute
* of column \'MRP Date\' to hide it on the report.
  LOOP AT tc_dlsam-cols INTO lst_cols.

*   If the column name equals to \'MDKE-DSDAT\'(MRP Date), proceed.
    IF lst_cols-screen-name EQ lc_column_mrp_date.

*     Set the \'Invisible\' display attribute of column \'MRP Date\' 
*     to true to hide it.
      lst_cols-invisible = 1.

*     Modify the table control deep structure \'COLS\' with the new
*     display attribute for column \'MRP Date\'.
      MODIFY tc_dlsam-cols FROM lst_cols
      INDEX sy-tabix.

    ENDIF.

*   As a best practice, clear the structure 
*   as its inside a loop.
    CLEAR:
      lst_cols.

  ENDLOOP.

ENDMODULE.                 \" F_HIDE_COLUMN OUTPUT
