Value type of numeric measures is implemented as Java integer so that max value is 2^31-1.
Long type should be used (max is 2^63-1).
The type of DB column PROJECT_MEASURES.VALUE should also be verified as decimal type is used. It does not accept Long.MAX value on all of our supported databases.
It is possible to respect this Long max value with this datatype => decimal or numeric (38,19) (2^63 before the comma and same range after it).
The direct change is possible in MYSQL (quite long) , MSSQL , POSTGRESQL.
The procedure to change the scale of a number columns in Oracle is much more complex (temporary column , move ...)
