| | Public Attributes (ttadv7114m000)Public attributes are used for the following
purposes: - As arguments in public methods.
- As entry points for external applications to the data of the
business object.
Note You cannot map public attributes directly to table fields or
to form fields. In stead, they must be mapped to protected attributes that, in
turn, are mapped to table fields or form fields. The protected attributes may
belong to the same business object/component as the public attributes or to a
related business object/component. If the protected attributes belong to a related business
object/component, the specific business object/component relationship details
must be specified. Prerequisites Before you can run the current session, you must have
defined protected attributes. Attribute The name of the attribute. The following rules apply to the attribute
name: - The name must be unique within the business object.
- The name must refer to business concepts and/or the
functionality of the business object. Do not use a name that refers to a
technical solution.
- Use standardized business terminology, for example, OAGIS.
- The name must be meaningful.
- Only alphanumeric characters ([A-Z], [a-z], [0-9]) are
allowed.
- Spaces are not allowed.
- If the name consists of one word, start it with a lowercase
character.
- If the name consists of several words, start each word,
including the first word, with a capital.
Example: customer,
OrderedQuantity. Domain The domain of the attribute. Domains are defined in the Domains (ttadv4500m000) session. Data Type The Data Type of the attribute's domain, e.g. String, Long or Double. Map Operator The Map operator for the attribute. Note If the map operator is Protected Attribute, you can specify only one attribute. If the map operator is Calculate, you can specify several attributes. Origin BO The three-digit identifying code of the business object of the linked protected
attribute. Origin Component The component of the linked protected attribute. If the business object of the linked protected attribute has no
components, this field is empty. Mapping The protected attribute that is linked to the public attribute
specified in the Attribute field. BO Relation This field is only available if you map a public attribute to a
protected attribute from a related business object. You must enter the position
number of a business object relationship detail line, which specifies the exact
relationship between the two business objects. You can zoom to the Relationship Details (ttadv7119m000) session. Default domain If you selected Protected Attribute in the Map Operator field, the default domain is that of the selected protected
attribute. If you selected Calculate or Not Applicable, this field is empty and you must specify a domain
manually. Override default domain If this check box is selected, you must manually
specify a domain for the attribute. You must enter this domain in the next
fields. Note If you selected Protected Attribute in the Map Operator field, the default domain is that of the selected protected
attribute. If you selected Calculate or Not Applicable, you must always specify a domain manually. Domain The package code of the domain. Domain The identification code of the domain. Data Type The Data Type of the attribute's domain, e.g. String, Long or Double. Use as XML Element If this check box is selected, the content of this
attribute will be read and interpreted as XML content. As a result, if you
clear this check box, the content is not interpreted as XML content. This
option allows you to communicate XML content while preventing that it is
automatically processed. This check box is only available if the Data Type of the domain of
the attribute is long. Read-only If this check box is selected, the value of this
attribute is controlled by LN, and you cannot change the value directly. An attribute can be read-only for various
reasons: - The attribute has a calculated value.
- External applications are only allowed to read the value,
and not to change it.
- The protected attribute linked to the public attribute
belongs to a related business object or component.
Note Read-only attributes that are not identifying can only be
used as output arguments, that is, as arguments that deliver
output. Identifier If this check box is selected, the attribute is part of
the identification of the business object. Mandatory If this check box is selected, the attribute must
always have a value. An attribute can be mandatory for various
reasons: - Attributes must be mandatory if they are mandatory input
for the standard method Create.
- If the public attribute is linked to a protected attribute
that is mandatory, the public attribute must also be mandatory.
Note that it is recommended to make a public attribute not
mandatory if it is linked to a protected attribute that is not
mandatory. Default available If this check box is selected, the attribute has a
default value. | |
