Technical field allows you to do similar thing as NO_OUT, you can hide the field on the output, the difference is that, users are not able to unhide this field. As NO_OUT, in order that TECH field work, you need to set its value to ‘X’.


Figure 70 ZDEMO_AIN_CL30 Setting of Field as Technical


Such setting is very helpful when you have to store some additional values in the internal table that supposed to be displayed, but you do not want to display them. Such field can be used for example during the event handling or displaying totals and subtotals.

It can also be used with the AUTHORITY-CHECK, just assume that you want to display one or two columns only to specific users that have the authorization for it ( like simple sales margin). After checking the authorization, you can setup the field as technical if user doesn’t have authorization to see it.

NO_OUT is useful when you want to hide the field on the output, but still allow users to unhide it on demand. As lots of fields from field catalog, it can be filled with ‘X’ or space (default).

If you set it to ‘X’, then as long as user will not unhide it and save it to the ALV variant, it will not be visible on the screen. But as said before it can be unhide using the display options.

In this case I’ve also filled the REPTEXT column, in order to show you that it is possible to move the columns to display. If I wouldn’t do that, then description would be empty.

As you can imagine from the name, NO_SUM does mostly opposite what DO_SUM, but in more secure way. If you don’t want that the field is allowed to be summarized, then set the value of this field to ‘X’. It will not only not show the sum, but also it will forbid to set it the GUI.


Figure 66 ZDEMO_AIN_CL28 DO_SUM for DISTANCE field


Once user will try to summarize the values of this column, he will get the message “Desired operation cannot be performed for column”.

DO_SUM is very helpful when you want to assure that some of the numeric fields are summarized directly after the output, without interaction from the user side. In order to do so, just put the ‘X’ or ABAP_TRUE into the value of this field in the field catalog.

One remark, if you’re adding this setting to value or quantity field, make sure that you also fill the QFIELDNAME or CFIELDNAME to have the sum of each unit or currency separately. In other case the values will be summarized without taking in consideration differences in the units.

FIX_COLUMN can be useful when you have a lots of fields in the field catalog and you want to make sure that some of the key fields are always visible, for example sales order number and position or posting document number. When you setup the value of this field to ‘X’, then the column(s) will be always visible. While scrolling the fields after the last field which has this flag will be moving left or right.

It is important to remember that it is not enough to say that for example 3rd column should be fixed. You must set this flag to all fields up to the last one, that should be fixed in order this setting work correctly.

Figure 61 ZDEMO_AIN_CL26 Setting FIX_COLUMN



Just make sure that you do not setup too much field like this, as it can happen that on small screens users will only see selected fields and nothing more.

When you’ll run the ZDEMO_AIN_CL26 program, you can see the behaviour of the FIX_COLUMN field. If you have wide screen, please resize the SAP GUI window, so the full grid is not visible.

EMPHASIZE allows you to change the colour of the whole column if there is such need.

This field can be filled with following values:

  • Space - this means you use the standard behaviour of ALV grid
  • ‘X’ – you use standard emphasize (default colour)
  • ‘Cxyz’ – where:
    •  ‘C’ is a character that notifies ALV grid that you will use specific colours
    • x – contains one of the following colour numbers:
      • 0 - background colour
      • 1 - blue
      • 2 - gray
      • 3 - yellow
      • 4 - blue/gray
      • 5 - green
      • 6 - red
      • 7 - orange  
    • y – is saying if the colours are intensified (‘1’) or not (‘0’)
    • z – is saying if the colours should be inverted (‘1’) or not (‘0’)

If you are familiar with the WRITE statement, then probably you know the EDIT_MASK addition which allows us to do formatting of the output in two different ways, you can apply the same to the EDIT_MASK of field catalog as well.

  1. Using Conversion-Exit, for example ‘==ALPHA’, where ‘==’ sings represents the information that we’re using conversion-exit, and the next 5 characters are reserved for the conversion-exit name.
  2. Using manual mask, where you can use following possibilities:
    1. Each underscore character (‘_’) in the mask will be replaced by the characters of the source field
    2. ‘LL’ on the beginning of the mask means that the underscore characters of the mask (“_”) will be replaced starting from left side, for example mask ‘LL__:__’ for value 123 will be displayed as ‘12:3 ’.
    3.  It’s also default setting for the mask so no need to use it in fact.
    4. ‘RR’ on the beginning of the mask means that the underscore characters of the mask will be replaced starting from the right side, for example mask ‘RR__:__’ for value 123 will be displayed as ‘ 1:23’.
    5. ‘V’ in case of quantity or amount fields is a place where the sign of the number should be displayed, for example mask ‘V__,__’ for number -1234 will be shown as ‘-12,34’.
    6. Any other characters will remain unchanged, means you can also build some extraordinary outputs, for example mask ‘Flight Number is: ____’ for the SFLIGHT-CONNID field will bring following result: ‘Flight Number is: 0017’.

When you set this field to ‘X’ then data will be display without using convertion exit that is assigned to the reference field. This setting works when you have REF_FIELD and REF_TABLE filled in fieldcatalog or when CONVEXIT field is filled. This setting is useful when you want to display internal values that are stored in database.
