Hello Ashok,

Check Table is a table which provides the number of possible entries along with the Validation.

But Value Table is a table which provides the number of possible entries along <b>without</b> the Validation.

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:

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.

check table is validation at field level.

value table is at domain level.

Value table is defined at the domain level and is used to provide F4 help for all the fields which refer to that domain.

Check table is defined against a field in SE11 if you want the values in that field to be checked against a list of valid values. For e.g. if you are using the field matnr in a table you could define MARA as the check table.

Also while defining a check table SAP proposes the value table as check table by default. Referring to the previous example if you tried to define a check table for the matnr field SAP would propose MARA as the check table.

hi,

... VALUE CHECK

Effect:

Ensures that the value entered in the field is checked against the check table or fixed values defined in the ABAP Dictionary. There must be a LIKE reference to an ABAP Dictionary field.

Note:

If there is a check table, the full foreign key check is generated. Consequently, all of the ABAP Dictionary fields involved in the check must be filled for the check to be meaningful.The check is also performed if the field is empty. You should therefore use the OBLIGATORY addition as well when you use VALUE CHECK.

Hi sr,

1. <b>what is the purpose / use ?</b>

-- so that the user can select values

from some master table , for that field !!!!

2. This is done by

CHECK TABLE (foreign key concept)

(and not value table)

3. When we create a check table for a field,

then

some DEFAULT table is PROPOSED

4. that DEFAULT table is nothing

but PICKED up from the domain of that field,

and shown from the value of VALUE TABLE.

(we can change it however)

regards,
