Avoid from user to delete data in internal table inside view

[Former Member]

HI ,

i have a VIEW and i want to avoid from the user the option to delete specific combination for that in the view code i keep the table extract before the modify and after and then i have 2 internal tables one with original data and the second with data after modifying.

i give example.

Assume i want to avoid from the user to delete the combination a1 b1 c1 mail.

and the user mark the line in the view to delete, i see in second table that i get mark sign.

itab before

field1  field 2 field 3 description 
a1       a2        a3              mail
b1       b2        b3              notif
c1       c2        c3              mail  
d1       d2        d3              notif
a1       a2        a3              task
 f1       f2         f3               notif


 itab after

field1  field 2 field 3   description  mark
a1        a2         a3           mail  
b1        b2         b3           notif
c1        c2         c3           mail
d1        d2         d3           notif
a1        a2         a3           notif       M
 f1        f2          f3            task  

Another thing i want to give the user option to delete the combination just if in the table

there is no entry with the combination but different description i.e.

if in the table i have for the combination :

a1 a2 a3 mail

a1 a2 a3 notif

the user can't delete it.

but if he have in table just one entire like below with description mail :

a1 a2 a3 mail

he can delete it .

what is the best way to do that ?

Hi Michael,

The best thing to do is to use [table maintanance events|https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/abap/how%20to%20implement%20events%20in%20table%20maintenance.doc].

I think in your case you can use 03 event - Before deleting the data displayed. In the routine you just check appropriate conditions like if certain combinations of records exists.

This should help you
