Modern SAP warehousing (EWM) makes me use old ABAP
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?
