Answer / suyog_sk

The Check Table is the dependent table to which the relationship is defined using foreign keys.
The contents of the check table field are shown in the input help for the referenced field.

This is nothing but a Parent & Child relationship.

As per DBMS what we call foreign key table, is called as check table in SAP.

The Value table is the table attached to a field at the domain level, where the entry to the field can be only from the value table.

Answer / sameera

Value Table

This is maintained at Domain Level.

When ever you create a domain , you can entered allowed
values. For example you go to Domain SHKZG -
Debit/credit indicator. Here only allowed values is H or
S.

When ever you use this Domain, the system will forces you
to enter only these values.

This is a sort of master check . To be maintained as a
customization object. This mean that if you want to enter
values to this table you have to create a development
request & transport the same.

Check table

For example you have Employee master table & Employee
Transaction table.

When ever an employee Transacts we need to check whether
that employee exists , so we can refer to the employee
master table.

This is nothing but a Parent & Child relationship . Here
data can be maintained at client level , no development
involved.

As per DBMS what we call foregin key table, is called as
check table in SAP.

There is 1 more important Difference in Value Table and
Check Table is that:

1. The contents of the check will be used as an input help
(F4 Help) for a particular field on which a check table is
assigned.
But the contents of Value Table are never used in Input
Help.

The Heirarchy which decides from where to used the Input
Help is:
1. Input help defined explicitly in ABAP Program or Dialog
Module.
2. Input Help Attached to the referenced Database Table
field.
3. Using the contents of Check Table as an input help if
neither (1) or (2) help are there.
4. Input help from Fixed value or Value range given in
Domain.

Answer / tony foster

A value table is defined in the "value table" field of a
domain. A value table becomes a check table when a
structure or table field defined using a domain with a
value table also has the foreign key relationship defined.
i.e The value table then becomes the check table for the
table/structure field
This is not to be confused with the fixed values or ranges
that can be defined in the domain in the value range tab.
This is not a value table, this is better described as an
in situ value list (All of these values for all domains are
stored in SAP tables DD07L & DD07T)

Hi all, For the past 1 year, I have been trying for job in SAP as a fresher, but no calls,no interviews.I know showing fake experience is unethical, but i dont have any alternative.After showing fake experience now iam getting calls,but still i feel guilty.Friends i have some questions. 1. If suppose i tell the truth in interview that i have shown fake experience,what would be the interviewer's reaction? Will accepting the fake go negative against me? 2.Whether i should accept the fake in technical round itself? (or) Maintain the fake,prove myself strong in technical round &then accept the fake in HR round? 3.Some of my friends(who have shown fake and well settled in MNC's ) are telling that during interview u should never accept as fake i.e., u should act confidently as a real experienced guy.Even if the interviewer come to know that u r a fake guy, but seeing ur confidence level ,he/she will select u ? Is it true? Friends, particularly interviewer's , HR's please give me ur valuabe solutions.Other's suggestions are also welcome.
