Fixed Value Ranges in Domain

Question

Hi all,
            i have create table in DDIC and use some domain in that. Now my problem is that there is a option in Domain which is Value Range.I am not able to find the reason why we use this in domain. Means what is the benifit of using Value Range ??
Hoping for the best solution.
Thanx,

Answer 1

The check table must have a key field which has the same domain as the check field of the foreign key table."
the above means that when I use domain(which contains value table ) the same domain must be there in check table .
Yes, the domain must be the same for check field (some field in ztable which you want input help for) and for key field of check table (which we match with check field).
I.e. when you look at table SPFLI you can see field CARRID (this is check field ) . Click on it and select Foreign keys (key icon button). You will see SCARR (this is check table ) and matching keys MANDT and CARRID (foreign keys for them are SPFLI-MANDT and SPFLI-CARRID). Then you go to check table SCARR and look at field CARRID.
The domain must be equal for check field (SPFLI-CARRID) and corresponding check table field (SCARR-CARRID). Only then the input help will be provided correctly.
So that means value table and check table are always same .
Not necessarly, but most often yes. This is because value table serves only the purpose of providing default table for foregin key relationship (when you want to define one), but you are allowed to change that assignment during relationship creation. No other "value" comes with using value table
By defining only value table i cannot get input help , i have to have check table
Correct!
Then what is the use of value table ?
As explained above, only for developer to have proposed this value table as a check table during foreign key definition.
whlile creating z field i can directly use a check table without defining a value table in domain.
Yes, you can. Nevertheless you will have to provide check table yourself. System will not suggest one.
Kindly explain me the use of value table in terms of adding zfield .
No sure if correctly understand you here. ZFIELD can use value table, but without check table it is useless. It will not provide you any input help, nor will check entry for that field when used i.e. on the screen.
If you still feel not good with above explanations please refer [url]When is Value table called?;url]
