When you create your first maintenance task list, it will be posted with a group number and a group counter number. The system saves each further task list you create for the same piece of equipment or within the same group will be assigned a counter.

Numbers for equipment and functional location task lists are assigned internally. When you have created an equipment or functional location task list, the system issues a message with the number it has assigned to the task list. The first task list you create for a specified piece of equipment or functional location will be identified by a group number and a counter number. Further task lists for the same piece of equipment or functional location will simply be identified by a counter number within the group.

Number assignment for general maintenance task lists works on the same principle as for equipment task lists. However, you can assign internal and external numbers to general task lists. The group number is more important for general maintenance task lists as it is used to access the task list.

If you use external number assignment for the general task lists in your company, you must specify an alphanumeric or numeric group identification for the general task list. This number must not have been previously assigned and it must be within the number range defined for your company. The number range for general maintenance task lists in your company is defined using the customizing function. If you want to know which numbers are valid for your maintenance task list type, contact your SAP Systems Administrator.
