Codes and Enums

SAP B1 coded-value reference — the DocObjectCode / object-type table (oOrders=17, oInvoices=13, …), BoStatus, BoYesNoEnum, and document-type enums used in Service Layer filters.

SAP Business One is coded throughout: booleans are enums, document types are numeric object codes, and statuses are named enum members. The Service Layer metadata defines 409 EnumTypes. In an OData filter you use the enum member name as a quoted string — not true/false, not a raw integer. This reference collects the codes you meet most often.

$filter=DocumentStatus eq 'bost_Open' and Cancelled eq 'tNO'

DocObjectCode — the document type identifier (`BoObjectTypes`)

There is only one Document entity in the Service Layer; every marketing document is distinguished by its DocObjectCode. This is also the value used as a line’s BaseType in the copy chain (see the Document Line Fields reference). Both the enum name and its integer are given — the integer is what appears in BaseType.

BoStatus — document status

The lifecycle state of a document (DocumentStatus on the header). The two everyday values are Open and Closed; Paid and Delivered appear in specific contexts.

Member	Integer	Meaning
`bost_Open`	0	Still live — not fully copied forward, not fully paid, not closed. The backlog / open receivables.
`bost_Close`	1	Finished — fully drawn forward, paid, or manually closed. Excluded from open balances.
`bost_Paid`	2	Fully paid (payment contexts).
`bost_Delivered`	3	Fully delivered (delivery contexts).

$filter=DocumentStatus eq 'bost_Open'

BoYesNoEnum — the boolean type

All boolean fields use this enum, not true/false. It appears on flags like Cancelled, SalesItem, InventoryItem, BackOrder, ManageSerialNumbers, and many more.

Member	Integer	Meaning
`tNO`	0	No / false
`tYES`	1	Yes / true

$filter=Cancelled eq 'tNO'

BoDocumentTypes — item vs service document

Set on the header’s DocType; decides whether the document’s lines carry items or post directly to G/L accounts.

Member	Integer	Meaning
`dDocument_Items`	0	Item document — lines carry `ItemCode`, affect stock.
`dDocument_Service`	1	Service document — lines post to a G/L `AccountCode`, no stock.

BoCardTypes — Business Partner type

The kind of partner (CardType on the BP master). See the Business Partner Fields reference for the full C/S/L meaning.

Member	Letter	Meaning
`cCustomer`	C	Customer — you sell to it.
`cSupplier`	S	Supplier / vendor — you buy from it.
`cLid`	L	Lead — a prospect, not yet a customer.

ItemTypeEnum — item type

Set on the item master’s ItemType (see the Item Fields reference).

Member	Meaning
`itItems`	A tradeable item (stocked when `InventoryItem = tYES`).
`itLabor`	Labour / service time — no stock.
`itTravel`	Travel cost — no stock.
`itFixedAssets`	Fixed asset.

How enums appear in filters — the rules

Quote the member name. DocumentStatus eq 'bost_Open', not eq 0 and not eq bost_Open.
Booleans are enums. Cancelled eq 'tNO', never eq false.
BaseType uses the integer, because it is stored as Edm.Int32: BaseType eq 17 (an order), not 'oOrders'.
Dates are strings, not enums, but share the “quote it” rule: DocDate ge '20250101' (format yyyymmdd).
