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.

Page 4: Domains in IBM Maximo Asset Management

Domains Application

From Go To menu choose: System Configuration

Platform Configuration Domains

Page 5: Domains in IBM Maximo Asset Management

Domain Types

Following domain types are available: Alphanumeric Numeric Numeric Range Table Crossover Synonym domain

Page 6: Domains in IBM Maximo Asset Management

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

Page 7: Domains in IBM Maximo Asset Management

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

Page 8: Domains in IBM Maximo Asset Management

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

Page 9: Domains in IBM Maximo Asset Management

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

Page 12: Domains in IBM Maximo Asset Management

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

Page 13: Domains in IBM Maximo Asset Management

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

Page 14: Domains in IBM Maximo Asset Management

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.

Page 16: Domains in IBM Maximo Asset Management

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:

Page 18: Domains in IBM Maximo Asset Management

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
