# Mandatory EcENTITY table fields

* bulk\_id

for 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 ent\_class\_id = ‘CUSTENT’ - ie. only for Custom Object entity, refers the type of CustomObject; ask CAD Studio consultant to provide this string value

* name

for example Vault Item number, Vault File name, Vault ECO number, Vault Folder name, …

* comm\_dir

1 for import into Vault

* comm\_status 0 for pending

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.holixa.com/holixa-erp-connector/data-interface-reference-manual/mandatory-ecentity-table-fields.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
