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.

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.

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.

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.

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.

Check Table: It is used to establish foreign key relationship and for field level checking.

Value Table: It is used to establish the range of values that an object can take.

hi bhaskar,

check table is nothing but field level checking..

check table:

Table whose key fields are used to check the foreign key fields (see Foreign Keys). Only entries that are contained in the key fields of the check table can be contained in the foreign key fields.

The check table is used to check whether the input values are valid and for the input help (F4 help).

where as value table is domain level checking...

value table:

In some cases you already know when you define a domain that all the fields referring to this domain should be checked against a certain table. This information can be stored in the domain by entering a value table.

The system proposes the value table as check table when you try to define a foreign key for this field.

hope this may be usefull..

please reward in case useful...

regards,

prashant

Hi,

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.

Hi,

Check Table is for Field level Validation whereas Value table is for Domain Level Validations.

Value Table proposes table for check table.

I think you are clear with this.

more elaborate.

**************************

Check Table

The Check Table is the table used by system to check if a data exist or not exist.

While creating a table if you want to be sure that a field can have some values

and these are in a certain table, you can give IT this table as CHECK 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.

Differences:

1)check table will carry out the check for input values for the table field being entered in any application

and value table will provide values on F4 help for that table field.

2)The check table defines the foreign keys and is part of the table definition.

The value table is part of the domain definition.

Hi,

In one line check table is used to establsh foreign key relationship in form of search help at field level that is it proposes help base on field level whereas value table is used for same purpose but here search help is proposed in the form of table containing valid field values.

Check table is assigned by foreign key relationship(a tab just above table).

Value table is option at bottm of the table screen.

Pls reward helpful points.
