How to create dynamic ON CHANGE statement? Please help!

Hi Experts,

I have a requirement where my ON CHANGE criteria is dynamic. It is based on wa_charakeyfrmt-value which I am reading from a table. If it is 'DO' then ON CHANGE will have wa_errtabcopy-DO. Else if it is 'LI' then ON CHANGE will have wa_errtabcopy-LI. There will be many cases like this. So instead of writing so many IF/ELSE or SWITCH/CASE conditions is it possible to dynamically create ON CHANGE criteria for the last field. See the example code below:

IF wa_charakeyfrmt-value = 'DO'. "On DO change

LOOP AT i_errtabcopy into wa_errtabcopy

WHERE sold_to = wa_errtab-sold_to.

ON CHANGE OF wa_errtabcopy-key_value

OR wa_errtabcopy-rep_created_date

OR wa_errtabcopy-rep_created_time

OR wa_errtabcopy-rep_counter

OR wa_errtabcopy-DO.

ENDON.

ENDLOOP.

ELSEIF wa_charakeyfrmt-value = 'LI'. "On LI change

LOOP AT i_errtabcopy into wa_errtabcopy

WHERE sold_to = wa_errtab-sold_to.

ON CHANGE OF wa_errtabcopy-key_value

OR wa_errtabcopy-rep_created_date

OR wa_errtabcopy-rep_created_time

OR wa_errtabcopy-rep_counter

OR wa_errtabcopy-LI.

ENDON.

ENDLOOP.

Hi Anupama,

Can you explain what do you mean?

It will be great if you can give some sample code.

Thanks

Hi

I dont think there is any dynamic calling of fields using on change of statement. Instead of on change of you can use at new (<field name which you wish to mention>).

END OF text.

DATA: string1(4) TYPE c, string2(4) TYPE c.

DO 4 TIMES VARYING string1 FROM text-word1 NEXT text-word2.

WRITE string1.
