Hi

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 ,

They both serve nearely the same purpose .

Check Table is a table which is used to check if the value exists in the table or not. It may not neceserayyl be a master table , for e.g. in some cases an entered value will be valid only if it exists in another table .

Where as value table is a table which is basically the master table and conains all the valid values for that feilds maintained in the table. So if a value for this is maintained in the system then it will surely be in this table , where as in case of check table it is not the case.

Hi,

Check table is assigned using the Foriegn key relation ship. Value table is assigned at the domain level. Both are used for populating F4 list. But Check table comes before the Value Table when list for populating F4 values needs to be created.
