On this tab the following fields can be viewed:

 

hmtoggle_plus1Add

The user must have a security profile linked to the function Part Operations with an access allowed of Add.

On add of a part operation the function will disable all fields except operation number, description, type of operation, designer, effective date, sequence and work centre.

Once the operation type is selected the function will act as follows:

IF the operation type is not equal to P or B, then all other related fields will be enabled.

IF the operation type is P or B, all other fields will be disabled until the work centre has been selected in the combo.

 

The "Add" button is only enabled when an operation, that does not yet exist for the part, is entered.  When the "Add" button is clicked, the operation is added to the selected part.

hmtoggle_plus1Assembly Illustration

It is populated with the part number and description from the Part Master table.

 

The number of characters to be entered before the list is shown is governed by the value of "populate length".

 

It is a reference to a part number that is an assembly illustration, document number, or another resource of the new or selected operation.

hmtoggle_plus1Batch Calculation Method

This is used in calculating the operations lead time. The system allows two interpretations regarding the setup and run time (I.e. when using elapsed time run hours):

 

Batch_Calculation_Method = 'B' (Batch Size)

This means that the setup and run times applies to a batch and therefore the lead time of the operation will vary according to the number of batches in the order quantity.

 

Batch_Calculation_Method = 'O' (Order Quantity)

This means that the setup and run times applies to the total order quantity. The lead time of the operation will not vary according to the number of batches in the order quantity. (I.e. it takes 10 minutes to run this operation, no matter how many were ordered).

hmtoggle_plus1Batch Size

It defaults to one and indicates the number of items to be processed together for an operation.

 

If Run Hours is type Elapsed (E), the run time/hours is the standard time required to process the complete batch.

 

If Run Hours is type Time per Piece (T), the run time/hours for the total batch is the Run Time * Batch Size i.e. run time as specified, is the standard time required to process or manufacture one item.

hmtoggle_plus1Change

The user must have a security profile linked to the function Part Operations with an access allowed of Change.

 

The "Change" button is only enabled when an existing operation is selected.  When the "Change" button is clicked, the Part Operations table is updated.

The ECP field is populated with approved ECP numbers where the type of change is specified as Change.

hmtoggle_plus1Complete Before Next

This means that this operation will have to finish before the next operation can start. If set, it will ignore the process batch quantity.

hmtoggle_plus1Cost Ratio

The COST RATIO is used to multiply the cost on the operation with the specified Ratio. This is used if the run time is specified in such a manner that it covers the Operation duration but Multiple resources are being used in order to perform the operation. To cost the operation at the correct rate, the Cost Ratio specified will be used to extend the cost of the operation to include the cost of the number of resources.

The default value of the Cost Ratio is 1.00000 and, in order to get the desired result, the user must enter a ratio other than the default if applicable.

hmtoggle_plus1Delete

The user must have a security profile linked to the function Part Operations with an access allowed of Delete. The "Delete" button is enabled when an existing operation is selected.  This operation will not be performed if:

 

There are failure repair tasks linked to the operation.

There are product structures using this operation as a repair task.

There are product structures using this operation as a "Deliver to Op".

 

The operation(s) to be deleted will be deleted from the, Task Facility Requirements table, Task Skill Requirements table, and the Task Resource Requirements table.

 

If the field ECP Control Part Operations on System Configuration has a value of:

6.  "PM", ECP control is applied if the development cycle of the selected maintained parent part is "PM", "PP" or "OBS".

 

The ECP field is populated with approved ECP numbers where the type of change is specified as Delete.

hmtoggle_plus1Description

It is a short narrative description of the selected operation.   It is an alphanumeric field where the he length must be between 3 and 255 characters (mandatory). On add of an operation and if for the work centre selected a default description exists in the table "Work Centre Part Ops Default" then this description will be defaulted to this field. The default description can be changed if the user has the correct change rights.

hmtoggle_plus1Designer

It is populated with the surname, first name, middle initial and employee ID from the Employee Master table where:

 

The status is Active (A) or Unavailable (U), and The employee is indicated as the Company designer.

 

The number of characters to be entered before the list is shown is governed by the value of "populate length".

hmtoggle_plus1Frame Backflush Material

Frame Backflush Material

If the user wants components that are required on this operation to be automatically issued when a quantity is specified as completed when this operation exists as an order operation then the user must select in the field Backflush Material On Completion one of the options.

No Backflushing will be the default.

For external operations the value can be only "No Backflushing" and the field will be disabled.

If No Backflushing is selected then no division and store can be selected.

 

Division

If the option selected is not "No Backflushing" then a division must be selected.

If the work centre referenced on the operation has a division specified then this division will be defaulted.

 

Store

If the option selected is not "No Backflushing" then a Store must be selected.

The field will be populated with all stores belonging to the division selected where the store participates in backflushing.

If the work centre referenced on the operation has a store specified then this store will be defaulted.

hmtoggle_plus1Ignore Calendar

If Ignore Calendar is ticked, the operation will be scheduled even on non-working days or shifts. These are operations that occur regardless of working times like for instance, paint drying time.    

hmtoggle_plus1Long Description Button

A button "Long Desc" was added on the tab Operation Maintenance. When clicked it will open a function in which the user can enter or maintain data.

hmtoggle_plus1Notes

This is a description field which can be used to describe a operation. It may be used to elaborate on the sequence, tooling etc.

This is an optional 255 character field.

hmtoggle_plus1Operation

It is used to identify the operation for a selected part.

 

When entering a new operation number, all the fields are cleared.  It is a mandatory alphanumeric field with a maximum length of 10 characters.

hmtoggle_plus1Process Batch

This is used in scheduling. It indicates when the next operation can start. The process batch tells us how many units this operation has to complete before the next one can start. This is dependent on the next operations work center's scheduling method. If the value of this field is E (early start) then when scheduling, the next operation will start as soon as this operation has completed its process batch quantity. If the value is M (minimum setup), then the next operation will start as soon as this operation has finished the next operations process batch quantity.

hmtoggle_plus1Run Hours

Provides two options namely, Elapsed (E) and Time per Piece (T).

 

Elapsed is the standard time it takes to process a batch of parts.  Time per Piece is the standard time it takes to process one part.

 

If Run Hours equals Elapsed (E), run time is divided by the batch size to calculate the standard time per unit.

 

If Run Hours equals Time per Piece (T), run time is the standard time per unit (batch size is only used for scheduling purposes).

hmtoggle_plus1Scheduled And Costed Code

Scheduled

When checked, it indicates that an operation is included in scheduled routing.  When unchecked, it indicates that an operation is excluded from scheduled routing.

 

Costed

When checked, it indicates that an operation is included in the cost calculation (cost generation).  Parts operations linked to a phantom part will be costed if checked.  When unchecked, it indicates that an operation is excluded from the cost calculation (Cost Generation).

 

Capacity Load

This indicates whether the operation constitutes load on the work centre.  An operation, like cleaning a machine, does not constitute load.

hmtoggle_plus1Scrap %

Gives an estimate of the percentage scrap expected during a part's specific operation.  A valid value must be between 0 and 99.

 

If the scrap percentage of a part is, for example, 10%, it is expected that every 1 out of 10 deliverables of this part operation will be scrapped.

hmtoggle_plus1Setup Hours

It is the time needed to prepare in order for a manufacturing/repair process to start.  It may include run time and inspection time for the first piece.

 

The minimum intervals are 10 seconds.  It is the same as setup lead time.  It is a numeric field that must have a minimum value greater than zero and a maximum value less than 59.9.

hmtoggle_plus1Sequence

Indicates the sequence in which operations are to be performed within a part routing.

hmtoggle_plus1Status

Provides two options namely, Active (A) (Default) with an effectivity date less than the current date and Inactive (I) with an effectivity date greater than the current date.

 

It indicates whether the operation is active or inactive.

hmtoggle_plus1Start On

This forces the operation to start at the beginning of the next day, or shift, provided shift calendars are used.

 

If for the next Operation Start On = Day 'D' : The next operation will not start even if there is still enough time in the day. It will start the next day. The process batch will be ignored.

 

If for the next Operation Start On = Shift 'S' : The next operation will not start even if there is still enough time in the shift. It will start the next shift. The process batch will be ignored.

 

If for the next Operation Start On = Scheduled Date 'N' : The next operation will be scheduled as normal (using process batch or complete before next if set)

hmtoggle_plus1Type Of Operation

Provides four operation type options, namely, Maintenance (M), Production (P) (default), Both Maintenance and Production (B) or Operator Task (O).

 

It is used to differentiate between production operations, preventative/corrective maintenance tasks and operators tasks.  Some operations are used for both maintenance and production and are classified as such.

 

Operations that are classified as Maintenance and, as both Maintenance and Production are used for Repair Orders of parts identified, on the Part Master as Repairable.

hmtoggle_plus1Work Centre

This field is  populated with all active work centres from the Work Centre table.

Where the operation being added has a type of P (Production) or B (Both, Production and Maintenance) and the work centre exist in the table Work_Centre_Part_Ops_Default the default values of the work centre will be displayed and the fields will be enabled/disabled according to the user’s profile.

 

The user will also not be able to change the current work centre to a work centre that has been flagged as inactive on the work centre table. A front end error message will be displayed.

On selection of a different work centre than the current work centre and the new selected work centre exist in the table Work_Centre_Part_Ops_Default the default values of the new work centre will be displayed and the fields will be enabled/disabled according to the user’s profile.

hmtoggle_plus1Queue Hours

The Queue Hours will be used (added) when calculation the estimated start and end dates of order operations that are auto inserted by the system

The queue hours will not be used when calculating operation costs.

hmtoggle_plus1Target Setup Hours

Target Setup Hours is only used as information as to what the ideal set up hours should be for the specific operation.

hmtoggle_plus1Target Run Hours

Target Run is only used as information as to what the ideal run hours should be for the specific operation.
