Hi,

Check table is one which is used as a reference table to get any search help in the form of foreign key relationship for a particular field element.

Value table is another form of reference table within check table for assigning field help with proposed value list for fields.

Hi,

Differences between check table & value table:

<b>Check table</b> contains key fields that are used to check the foreign key fields. 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).

When ever we create a domain , we can enter allowed values. When ever we use this domain, the system will force us to enter only these values.So a <b>value table</b> is the one which contains all the valid values for a field.It is maintained at the domain level.

The <b>major difference</b> between these two tables is the contents of the check table will be used as an input help(F4 Help) for a particular field on which a check table is assigned whereas the contents of Value Table are never used in Input Help.

Reward if useful.

Hi,

Difference between a check table and a value table

<b>Value Table</b>

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.

<b>Check table</b>

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.

<u><i><b>Value Table</b></i></u>

In some cases you can see when you define a domain that all the table fields or structure components 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 the field or component. This proposal can be overridden.

Domain S_CARR_ID (data type CHAR, length 3) in the flight model describes the three-place code of the airlines. All the airlines are listed together with their codes in table SCARR. It is generally advisable to check fields referring to domain S_CARR_ID against table SCARR. SCARR is therefore entered as value table for domain S_CARR_ID. If you want to define a foreign key for a field referring to S_CARR_ID, SCARR is proposed as the check table.

A check is not implemented by simply entering a value table! The check against the value table only takes effect when a foreign key has been defined.
