When creating a new custom field of type ‘Number’ using Personalization, a new column will be added to the table with a data type of ‘bigint’.

When creating a new Attribute of type ‘Integer’ with a range, creating a new table constraint of type ‘System defined,’ and mapping against the system table, an error message is triggered preventing the process: ‘'The selected field does not match any of the supported types; Enum, String, and Integer'.

It is not possible to map to an integer (number) field in ‘System defined’ table constraints within Product configurator.
Mapping is allowed to number fields with data type 'int', however not 'bigint'.

Changing the current way the system is working would provide a great amount of help and flexibility to users when making use of product configurator module.
