The Get verb is to communicate to a business software component a request for an
existing piece or pieces of information to be returned. The Get may be paired with most
of the nouns defined in the OAGIS specification.The response to this request is the Show
verb. The behavior of a BOD with a Get verb is quite predictable across the nouns it is
paired with.The Get is designed to retrieval of information by using that information's
primary retrieval field, or key field. The Get verb may also be used to request several
documents at once. Selection Criteria:There are two types of selection capabilities for
most BOD's that use the Get verb.1) The first selection capability is called Field-Based
Selection. Within a Get-based Business Object Document, the first Data Type that occurs
in a specific BOD structure is commonly used to provide the Field-Based Selection
criteria. This is always defined within the specific BOD and is commonly the required
fields for that specific Data type.The Field-Based Selection enables the requester to
provide a value or values (in the case of multiple required Field Identifiers), in the
required fields. Then the responding component uses those values to find and return the
requested information to the originating business software component.2) The second type
of selection capability for Get-based BODs is called Data Type Selection. Data Type
selection enables the requester to identify which Data Types within the noun are
requested to be returned in the response. The use of this capability is described for
each corresponding Data Type for all BODs that use the Get verb. The Data Types are
identified for retrieval within the Get instance of a BOD by including the name of the
Data Type in the meta data but without any Field Identifiers or Segments identified
within the Data Type. This will signify to the responding application that all of the
data that corresponds to that Data Type is to be included in the response.If the Data
Type is not requested, the Data Type identifier is not included in the Get request and
this will signify to the responding component that the Data Type is not to be returned.
