Rules for setting the WBS code format

Whether you define the WBS codes manually or use the table in the Define WBS Format dialog box, the codes must comply with these rules:

  • The format must be defined with a minimum of 2 levels and a maximum of 10 levels.
  • The last character in the format defines what is used for all remaining levels in the schedule tree structure.
  • The format must be defined in both master schedules and subschedules. The format is not supported across schedules.
  • The overall initial value cannot exceed 32 characters.
  • The maximum size for an individual level set in the initial value is 12 characters.

Note: Teamcenter displays an error message if these rules are violated.
