Where Domains are used
Domains create list of values, which can be used to enter the information in the Maximo fields and classification attributes.
The user can choose the values from the domain list or enter them manually.
Object having a domain attached can accept only values from that domain (manual values are also validated). This mechanism introduces data standardization and prevents entering wrong information.
Creating Domains
Because the domains are closely related to the database structure it is advised to leave domain management to the system administrator. Wrong domain length and type may cause errors.
Domains Application
From Go To menu choose: System Configuration
Platform Configuration Domains
Domain Types
Following domain types are available: Alphanumeric Numeric Numeric Range Table Crossover Synonym domain
How Domains work
Most of the domains contain pair of information: Value (saved in the field in the application) Description (used to choose the value from the list –
not saved in the field).Fields Organization and Site define the
filtering of values for each company’s branch.View/Modify Conditions button defines the
rules to hide/show domain values based on conditional expressions
Alphanumeric Domain
Alphanumeric domains contain list of static values including letters, digits and other characters e.g. YES – Positive answer NO – Negative answer
Data Type: Lowercase: domain values will be always saved in
lowercase e.g. true, false Uppercase: domain values will be always saved in
uppercase e.g. TRUE, FALSE Alphanumeric: values will be saved exactly as the user
typed it in e.g. True, False
Numeric Domain
Numeric domains contain list of static values including digits, dot and minus sign e.g. 1 – Positive answer 0 – Negative answer
Data Type: Duration in hours e.g. 1:45 Amount in currency (only two decimal digits are allowed) Integer value: from -2147483648 to 2147483647 Small integer: from – 32768 to 32767 Decimal value Floating value
Numeric Range Domain
Numeric domains do not define the lists of allowed values but rules: which numbers are allowed e.g. Values from 0 to 8 Values from 0 to 100 with an interval 10 so only 10, 20, 30…
can be enteredData Type:
Duration in hours e.g. 1:45 Amount in currency (only two decimal digits are allowed) Integer value: from -2147483648 to 2147483647 Small integer: from – 32768 to 32767 Decimal value Floating value
Numeric Range Domain cont.
You define following parameters of the domain: Segment id (integer value) – you can have multiple
segments for example with different intervals Minimal value Maximal value Interval – defines discrete values for the above range.
If you leave it empty, a continuous range of values will be used – depending on the data type: For integer values it will be allowed to enter: 1, 2, 3… For decimal domain with 2 digits precision you can enter:
1.01, 1.02, 1.03...
Table Domain
Table domains are used to present data from other application. The list of records can be filtered out.
You define following parameters of the domain: Object e.g. WORKORDER List Where Clause – condition to present the data from
above object Validation Where Clause – condition to check the content
of the field with attached table domain Optionally you can define Error Message Group and
Error Message Key to display an error message if value does not match domain
Crossover Domain
Crossover domains do not provide list of values, instead they are used to return a value from a field in one application which will be saved in a field in another application.
You define following parameters of the domain: Object e.g. WORKORDER List Where Clause – condition to find the data in the above
object Validation Where Clause – condition to check the content of the
target field Optionally you can define Error Message Group and Error
Message Key to display an error message if value does not match domain
Crossover Domain cont.
Parameters of the domain cont.: Source Field – field from the above object (chosen
from the list) Destination Field – field in current application to
which the value from source field will be copied (entered manually!)
Accept NULL Value? – defines if the target field can be set to null
No Overwrite? – defines if the target field can be overwritten
Sequence – defines the order for copying the values
Crossover Domain cont.
You should not attach this domain to the destination fields, but to the field which triggers an update.
For example you may have a domain, which will copy information from Primary SMS field in People application to new field SMS Number in Work Order Tracking. We want this to happen after Supervisor field gets populated. In the above case the domain should be attached to Supervisor field not to SMS Number.
Synonym Domain
Synonym domains are system domains. You cannot create new domain of this type, it is only possible to define new aliases for existing internal values.
Synonym domains are used for example to define statuses in applications. Maximo uses internal values in predefined workflows.
For example you can define an alias DRAFT for WAPPR status in WOSTATUS domain to indicate that this work order is still in early stage.
Synonym Domain cont.
You define following parameters of the domain: Internal Value – you should use one of predefined
values Value – here is the place for your alias Description – information about alias
How to find a Domain
One field can have only one domain attached. To find it you should first identify the field name in the database. This information is available via Context Help. Press ALT-F1 or ALT+I when the cursor is in the field.
Maximo displays the field name. For example: field Type in Assets application is called ASSETTYPE and is located in ASSET table:
How to find a Domain cont.
Open Database Configuration application, search for the table ASSET and check the name of the domain attached to the field ASSETTYPE
