Sets whether the field value should be automatically incremented.
Yes if the field value is automatically incremented; otherwise, No. The default value is Yes.
If you want to manually assign a value to a field that has the AutoIncrement property set to Yes, you must be member of the SQL Server db_owner database permission set.
A table can only contain one auto-increment field. The numbers assigned to this field will not always be consecutive for the following reasons:
If you delete some records from a table, the numbers used for these records are not reused.
If several transactions are performed at the same time, they will each be assigned a different number. However, if one of these transactions is rolled back, the number that it was assigned is not reused.
If you add an auto-increment field to an existing table, the field automatically generates consecutive values and inserts them into the table. If you enable the AutoIncrement property for a field that already contains data, there must be no zero values in the field.
The AutoIncrement property is designed to always assign numbers automatically. If you want to insert a record, be sure that the value in this field is blank before you insert the record.
The AutoIncrement property does not work with Dynamics NAV temporary tables.
