Hi,

check table : mainly used for referential integrity purpose in foreign key relationship.it contains all the primary key values of field [primary key] of a data base table.

value table: contains a list of values . value table can be attached to a domain of a table filed by which user can select any one of existing values from that value table.

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,

Value Table

This is maintained at Domain Level.

When ever you create a domain , you can enter 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.

Difference in Value Table and Check Table

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

Reward Points if it is Useful.

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.
