Translated messages and labels are not enabled by default on Maximo workflows. This means that if you have a multilanguage environment all the users will see the same task descriptions interaction messages when using workflows.
To be able to insert translated labels and messages for workflows you have to enable the multi-language option for the following attributes:
To set multi-language option go to System Configuration > Platform Configuration > Database Configuration find each attribute and set the ‘Multilanguage in use?’ flag. Enable the admin-mode and apply database changes.
After having done this you should be able to login as MAXADMIN with a different language and set different labels for actions and tasks using the standard ‘Workflow Designer’.
