What is the difference between value table and check table?

Answer Posted / tony foster

A value table is defined in the "value table" field of a
domain. A value table becomes a check table when a
structure or table field defined using a domain with a
value table also has the foreign key relationship defined.
i.e The value table then becomes the check table for the
table/structure field
This is not to be confused with the fixed values or ranges
that can be defined in the domain in the value range tab.
This is not a value table, this is better described as an
in situ value list (All of these values for all domains are
stored in SAP tables DD07L & DD07T)
