Difference between check table and value table: The 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. Consider a Table T (Another database aTable) which behaves as a Value Table and Check Table at different Situations. Case 1.
When the field F is a primary key for the database table DBT, the table T behaves as a Value Table. We can enter a new value for the field F and values for field F flow from table T the database table DBT. Learn the difference between check table and value table in SAP ABAP, with examples and explanations.
Check table is a parent-child relationship, while value table is a domain. Learn the difference between check table and value table in ABAP, two concepts of table validation. Check table is a table of valid entries for a field, while value table is a table of valid entries for a domain.
It is maintained at the Table level. Check table provides a list of possible entries. we can not provide any value other than value other than possible entries.
In SAP, check tables and value tables are used within the Data Dictionary to enforce data integrity and provide valid value sets for table fields. Check tables and value tables are both used for validation in ABAP. Value tables define allowed values at the domain level and must be maintained through a transport request.
Check tables validate values at the field level by checking if a value exists in a referenced table. While value tables restrict input values, check tables can also be used to provide input help by displaying the values. 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. Also Check this info.
Check Table: 1. It contains valid entries of a particular foreign key. 2.
Check table is validation at field level. 3. It is part of table definition.
Value Table: 1. It is part of domain definition. 2.
Value table is validation at domain level. 3. It is used to provide values on F4 help for all the fields which refer to that domain.
Table T1, which is the one being checked, is called a foreign key table, and table T2 is called a check table. The terms dependent (foreign key) table and referenced (check) table are also used. VALUE TABLE:If the domain of the check field has a value table, this is proposed by the system as check table in the foreign field maintenance.
