    Refer the links -

    check-table-and-value-table

    check-table-and-value-table

    You can get the info by doing F1 on any Domain->Value table field.

    Similarly When you goto Foreign key dialog then if you do F1 on Check table field you will get the info.

    Value table is mentioned at the Domain level, and it will be used to show the F4 help for the Data element that uses this DOmain.

    Also when you try to create a foreign key for a table field for which this Data element where this DOmain is being used then in the Proposal for the Foreign key you will get this Value table as the table aginst which you want your field's values to be checked agisnt.

    So Value table will be used as a Check table when you create Forigen key relationship for Foreign key table.

    Check table is the term used when you are defining Foreign key relationship.

    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 we define foriegn key in an value table then its is called as check table.

    Value table – It’s a field in a domain it helps in domain level data validation.

    Check table – unlike value table it helps in feild level data validation.

    Regards
