I am an ABAP developer.
And you might know that I claim to do “modern” ABAP.

But programming in a modern SAP warehousing solution – SAP EWM – makes me use old ABAP.
Like function modules.
And maybe even dynpros.

An example is the /SCWM/MON: the nodes have to be FMs, the methods as well.

Here is an example monitor method:

FUNCTION Z_MON_METHOD_PAINT_HU
  IMPORTING
    IV_LGNUM TYPE /SCWM/LGNUM
    IT_DATA TYPE /SCWM/TT_LIME_ALL_MON.

*Allow just 1 line
  IF lines( it_data ) <> 1.
    "Please select exactly 1 line for this method!
    MESSAGE s003 DISPLAY LIKE 'W'.
    RETURN.
  ELSE.
    DATA(ls_hu_data) = it_data[ 1 ].
  ENDIF.

*Ask for Input ("what colour to paint the HU?")
gs_hu_paint_dynpro-huident = ls_hu_data-huident
  CALL SCREEN c_screen_paint_HU STARTING AT 10 10 .
*make sure no cancel etc. 
  IF g_fcode NE c_fcode_save.
    RETURN.
  ENDIF.

* do the actual work in ABAP OO:
go_my_mon_node->paint_hu_in_colour( i_huident = gs_hu_paint_dynpro-huident 
				    i_colour = gs_hu_paint_dynpro-colour_to_paint ). 

ENDFUNCTION.

You know what: I think it’s not that bad, actually.

What do you think?
Do you use old ABAP?
Do you have to?

Best
