Work Order Operation Maintenance
Before a firm work order is started, the corresponding
operations can be deleted, cancelled or modified. In order to create a new
operation (i.e. an operation which is not mentioned in the initial manufacturing
routing), it is necessary to enter an operation number that places the operation
correctly in the operation sequence and afterwards to fill all the fields.
When an operation is removed, it disappears from the file.
Fields
All these fields come from the routing operation that was
used for the release.
|
Operation Id: |
Mandatory (three digits). If the number exists, the
operation is shown. |
|
Work center Id
Description
Set-up time
Preparation
labor time
Machine Run Time
Labor Run Time
Quantity per
time
Quantity per cycle
Move time
Fixed scrap
Proportional
scrap: |
Refer to the description of the Routing Operation page for the
meaning of the many different fields of this page. |
|
Counting point: |
The last operation has to be a counting
point. |
|
Machine Id: |
 If a
machine code has been assigned in the manufacturing routing, the code is
displayed in this field and is not modifiable. The Imposed box is
filled.
If the work order has been scheduled, this field
contains the machine code to which the operation had been allocated.
If the operation has to be processed on a specific
machine in a work center, it is possible to indicate the corresponding
machine code and then check the Imposed
box. |
|
Tool: |
 This field
specifies the tool to use for the operation. The referred tool must appear
in the Tool table.
|
Buttons
|
Library |
This
button displays the library operation list. To create an operation,
it is necessary to enter a new operation number, and afterwards to select
an operation in this list. |
|
Cancellation |
This button
cancels the operation in the order, without deleting it from the file. The
status of the operation is changed to Canceled. The operation will
be ignored in scheduling and in control.
Clicking again on the
Cancellation
button could reactivate
a canceled operation. |
|
Destinations |
This
button enables one to enter or to modify destinations of parts if network
routings are used. |

This page has three tabs:
•
the Times tab allows the modification or entry of the
manufacturing times,
•
the Control tab shows the quantities to process and the standard
hours,
The labor standard time is equal to the labor set-up time
plus the product of the order quantity by the labor run time (divided by the
units of time and the cycle time units).
The machine standard time is equal to the set-up time plus
the product of the order quantity multiplied by the machine time (divided by the
units of time and the throughput time units).
•
The Dates tab shows the scheduled dates, which are calculated by
the Material Requirements Planning function or by the Sched. button, as well as
the dates scheduled by finite capacity scheduling. The Waiting
time field contains the number of hours the batch must wait before being
processed on the planned start date.
