| # Work Order Activities (tswcs2110m000) Use this session to maintain work order activities. Work order activities can be based on the reference activities that are defined in the Activity Management module. If you do not use reference activities, you can identify the work order activity with a description. You can select a single reference activity, a master routing, a routing option, or an operation to plan and carry out maintenance on a (serialized) item. The master routing, routing option, and operation are identified by a reference activity. You can modify the default data that you defined for the reference activity in the Activity Management module, for example, activity duration, required materials, required hours, or required tools. The default transaction time for a new work order activity is the current time. The transaction time is also used to identify the version of the reference activities. In this session you can: Modify the planning times of the activity. Enter the actual times. Enter the actual result of an inspection. Add a routing to the work order activity line. Add resource requirements to a work order activity. You can add activities to a work order during the work order's planning phase, during the work orders preparation phase, and during the execution phase. The work order status must be Free, Planned, or Released. You cannot add activities to subcontracted work orders that have the Released status. Related topics To use reference activities Master routings and routing options Work Order The series code that identifies the work order. You can define the series for the work order number group in the First Free Numbers (tcmcs0150m000) session. The number group for work orders is set in the Work Order Parameters (tswcs0100m000) session. Related topics Number groups in Service Work Order The work order description is selected in the following order: The description of the service type. The description of the serialized item. The description of the item. The label description. Work Order Status The current status of the work order. The work order status is used to control the various phases of the work order process. You can change the work order status at any time if the status is Free or Planned. After the work order is released, all work order activities must be completed before the work order can be updated to the next status. Work Order/ Work Order Activity Status Item The item or serialized item on which maintenance must be carried out. Description The item description. Serial Number The serial number of the serialized item. Activity Line The activity line represents the reference activity or master routing that must be carried out for the work order. The activity line is identified by a sequence number. Activity Line The current status of the work order activity. The work order activity status is used to control the various phases of the work order activity process. The work order activities have an activity status that is related to the work order status. The following table lists the possible activity status values for each work order value.

You can change the work order status at any time if the status is Free or Planned. After the work order is released, all work order activities must be completed before the work order can be updated to the next status. Master Routing The reference activity that identifies the master routing, and is selected from the Reference Activities (tsacm1101m000) session. Note If the work order's item is serialized, the item's serial number must be within the master routing's serialized item ranges. The service department that is specified on the work order header must be linked to the activity group that is linked to the reference activity in the Activity Management module. The master routing is used if the Use Master Routing check box is selected in Work Order Parameters (tswcs0100m000) session. Related topics Master routings and routing options Sequence The sequence number of the work order's activity. Reference Activity The reference activity that must be carried out. You can enter a single reference activity or the reference activity that is specified for an operation in the master routing. Note If a main service department must carry out the work order, you can only select reference activities that are defined for the item that must be maintained and for the main service department in the Reference Activities (tsacm1101m000) session. You cannot modify the reference activity if the activity status is Released, Completed, Signed-Off, Closed, or Canceled. If the Reference Activity Mandatory check box in the Work Order Parameters (tswcs0100m000) session is selected, the reference activity must be filled in. The serialized item must belong to the serialized item ranges that are defined for the reference activity in the Reference Activities (tsacm1101m000) session. Effective Time The first date and time when the reference activity becomes valid. Note The effective time and expiry time are defined in the Reference Activities (tsacm1101m000) session and are change controlled. Execution Time The first date and time when the reference activity is no longer valid. Note The effective time and expiry time are defined in the Reference Activities (tsacm1101m000) session and are change controlled. Description The description of the work order activity. If you do not use reference activities from the Reference Activities (tsacm1101m000) session, you can manually enter a description to identify the work order activity. Note If you have entered a reference activity, the reference activity description is selected from the Reference Activities (tsacm1101m000) session. Search Argument The work order activities search argument. The search argument is derived from the description. Maintained Quantity The number of maintained items/parts which went successfully through one or all steps of the work order process. Work Center The work center in which the work order activities are carried out. You can link the reference activity's activity group to the work center: When you define a reference activity in the Reference Activities (tsacm1101m000) session. For example, cleaning activities that belong to the Cleaning activity group must be carried out in a work center where cleaning equipment is available. Checklist The checklist that can be used to carry out the work order activities. Finding Reason The code that identifies the result of the inspection. Findings Text If this check box is selected, a text was added to the finding reason. Related topics To use texts Signed-off By The service employee who signs off the activity. The employee must possess the required sign-off skills. Signed-off Time The date and time when the activity status was changed to Signed-Off. Earliest Start Time The earliest time when you can start to carry out the work order activity. The default value for the first work order activity is equal to the work order's earliest start time. For subsequent work order activities, the following formula is used to calculate the earliest start time (EST):
     EST current activity = EST previous activity + duration previous activity
Latest Finish Time The latest time when you can finish carrying out the work order activity. The default value for the last work order activity is equal to the work order's latest finish time. For previous work order activities, the following formula is used to calculate the latest finish time (LFT):
     LFT previous activity = LFT next activity - duration next activity
Appointment If this check box is selected, an appointment exists for the work order activity, and you can only modify the earliest start time and the latest finish time in the Appointments (tsmdm0123m000) session. Note The checkbox is cleared when the ATP check is performed and there is a changed in the planned start time. Related topics Impact of ATP Date ATP Date The ATP date when the specific spare part is available in the warehouse. Note When the ATP date is greater than the earliest start time then the earliest start time is set equivalent to the ATP date. The Planned Delivery Date is also changed to match the ATP date. The ATP date is not generated when: The ATP check does not generate any date. The Item is not present in the warehouse The master plan is not present When the item falls outside the range of the master plan horizon range. ATP Check Indicates when there is a change in the planned start time and appointment due to ATP check. Related topics ATP Queue Time The default planned queue time is equal to the work center's queue time. The work center's queue time is defined in the Service Departments (tsmdm1100m000) session. Queue Time The unit in which the time duration is expressed. The duration time unit is defined in the General Service Parameters (tsmdm0100m000) session. Setup Time The planned setup time for the work order activity. The setup time is expressed in the unit of time duration that is defined in the General Service Parameters (tsmdm0100m000) session. Labor Run Time The planned labor run time is expressed in the unit of time duration parameter. Machine Run Time The planned machine run time is expressed in the unit of time duration parameter. Activity Duration The order activity duration is the sum of the setup time and the run time. You can enter the machine run time and the labor run time. The largest of both run times is used to calculate the order activity duration. Example The setup time for an order activity is one hour. During the setup time, the maintenance employee prepares the order. The machine run time is three hours. During the first hour of the machine run time, the maintenance employee keeps the machine in operation.
