# Mandatory EcENTITY table fields

## bulk\_id

For the ITEM entity type import, it is strongly recommended to keep one *bulk\_id* for each item structure. I.e., when importing purchased items, unique bulk\_id should be assigned to every single item.

## ent\_class\_id

For example, ‘ITEM’.

## guid

Only for the *ent\_class\_id* = ‘CUSTENT’. I.e., only for Custom Object entity. It refers to the type of *CustomObject*; ask the Arkance consultant to provide this string value.

## name

For example, the Vault Item number, Vault File name, Vault ECO number, Vault Folder name…

## comm\_dir

1 for import into Vault.

## comm\_status

0 (pending).
