Hi,

check table is nothing but which has foriegn key relation,

value table is dont have foriegn key relation.

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.

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. They are not used in the Input Help.

Difference between a check table and a value table

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.

Hi,

When you use :

Check table 😆 you can not select any other value other than the ones in it.

Value table 😆 Possible values; Needn't neccesary be the ones from the table.

Cheers,

HI,

CHECK TABLE: IT IS NOTHING BUT THE VALUE ENTERED IN THE FOREIGN KEY TABLE IS CHEKED AGAINST THE CHECK TABLE.

VALUE TABLE: IT IS USED FOR GETTING F4 HELP.

IF U SPECIFY THE VALUE TABLE AND THEN IF CREATE THE FOREIGN KEY RELATION IT 'LL AUTOMATICALY GET ALL THE DETAILS.

IT IS MEAR OF GETTING THE VALUE AND THE VALUE IS NOT CHECKED.
