Bottleneck Scheduling

This activity allows you to sequence and schedule the activities on specific critical resource. Tell me more

Select the “Bottleneck Scheduling” link under the “Scheduling“ business component.

The “Bottleneck Scheduling” page appears.

Enter the following in the “Bottleneck Sequence Criteria” group box:

Resource No.	The number identifying the resource for which scheduling is done. Mandatory. The resource number cannot be left blank. The resource should belong to the selected department and should be in “Active” status.
	Help facility available.
Department	Use the drop-down list box to select the departments for which the login user has access permissions. The system retrieves all the departments in ascending order to which the login user is mapped.
Seq. Rule Code	Use the drop-down list box to select the sequence rule codes. Mandatory. The system retrieves all the available sequence rule codes in ascending order along with a blank row. If a particular sequence rule code is selected then you can identify the sequencing rules to be used for sorting or sequencing a set of work orders. The multiline details are retrieved using the selected sequence rule.
Due Date From	The starting date in the range of due dates based on which the work orders are retrieved. The system checks if the format is in the correct Date Format. The system retrieves all the orders created from within the specified range. The system displays “Blank” by default on launch of the page.
Due Date To	The ending date in the range of due dates based on which the work orders are retrieved. The system checks if the format is in the correct Date Format. The system retrieves all the orders within the specified range. The system displays “Blank” by default on launch of the page.

Note: Work orders between “Due Date From” and “Due Date To” are displayed.

Consider WIP	Select the checkbox to retrieve all the work orders that are already started that is., orders that are in “Order/Activity Started” status. If the checkbox is unchecked, then the system retrieves all the work orders in the “Requested”, “Accepted”, “Firmed” or “Released” status. If "Consider WIP" is enabled then the system also considers the activities that belong to the work orders having the status as " Order/Activity Started ". If the quantity is reported for the activity then the system computes the activity duration for the remaining balance quantity to be processed. The system computes the duration for the balance quantity as the sum of the setup time and (the run time per piece multiplied by balance quantity) and the batch time. The system leaves the box “Unchecked” by default on launch of the page.
Start Date From	The starting dates in the range of start dates based on which the work orders are retrieved. The system checks if the format is in the correct Date Format. The system retrieves all the orders created from within the specified range. The system displays “Blank” by default on launch of the page.
Start Date To	The ending date in the range of start dates based on which the work orders are retrieved. The system checks if the format is in the correct Date Format. The system retrieves all the orders within the specified range. The system displays “Blank” by default on launch of the page.

Note: Work orders between “Start Date From” and “Start Date To” are displayed.

Click the “Get Details” pushbutton to retrieve the bottleneck resource details.

The system checks either “Due Date” range or "Start Date" range is specified. If both the date ranges are specified, then the system displays an error message. The system populates the multiline based on the following criteria:

If start date range is specified then the system retrieves all the work orders along with the respective activities scheduled between the specified start date ranges on the resource that belongs to the department. The work order having status as “Accepted”, “Firmed” or “Released” and if “Consider WIP” is enabled then work orders with status as “Order/Activity Started” are retrieved by the system.
If due date range is specified then the system retrieves all the work orders along with the respective activities scheduled between the specified due date range on the resource that belongs to the department. The work order having status as “Accepted”, “Firmed” or “Released” and if “Consider WIP” is enabled then work orders with status as “Order/Activity Started” are retrieved by the system.

Enter the following in the “Bottleneck Scheduling Details” group box:

Use MRP Date	Select the checkbox to start scheduling on each activity of specific resource, which is scheduled on the specified resource number on the date suggested by the "MRP". The system leaves the box “Unchecked” by default on launch of the page.
Scenario	The code identifying the scenario defined for scheduling based on the sequence rule codes. Mandatory. The system displays “Blank” by default on launch of the page. The specified scenario should already exist and should be valid to retrieve the details. During, the creation of the scheduling, the scenario has to be specified .

Click the “Get” pushbutton to retrieves all the work order details in the multiline for the specified scenario.

Enter the following in the “Bottleneck Scheduling Details” group box:

Use Alternate Resource	Select the checkbox to identify the alternate resource. The system checks the availability of the mentioned resource and if the same is not available it schedules for an alternate resource. The system leaves the box “Unchecked” by default on launch of the page.
Use Base Date	Select the checkbox to start scheduling on each activity, which is scheduled on the specified resource number based on the base date. The system leaves the box “Unchecked” by default on launch of the page. If this field is checked then for scheduling each work order the system should consider the Base Date specified as the start date for all the work orders available in the multiline. For any specific work order if the Start By Date is specified then the system should ignore the Base Date for the specific work order and consider Start By Date as the start date.
Base Date	The base date from which the schedule need to be generated. This date will be considered only if Use Base Date is selected. If Use MRP Date is “Checked” then this field should be left blank. If Use Base Date is “Checked” then this field cannot be left blank and can be considered as the start date of the activity. For any activity in the multiline if the “Start By Date" is specified then the specified activity should not be scheduled before the start by date. The system displays “Blank” by default on launch of the page.
Schedule Online	Select the checkbox to execute scheduling either in online or batch mode. The system leaves the box “Unchecked” by default on launch of the page.

Check the box in the “Select” column of the multiline to select the bottleneck scheduling details.

Click the “Bottleneck Scheduling” pushbutton to schedule the bottleneck resources.

The system ensures that at least one record is displayed in the multiline. The system schedules the first activity in the sequencing list along with its respective sub-activities. For the selected activity, the system assigns the start date as the base date if the scheduling is based on the "Base Date" or the MRP date if the scheduling is based on the “MRP Date”. If for the selected activity "Start By" Date is specified then the activity can be scheduled not earlier than the date specified in the “Start Date By” field and assigns this date for the activity.

The system checks the selected activity is completely scheduled on the specified resource and checks whether any preceding and succeeding activities exists for the selected resource. If activities exist, then the system retrieves all the preceding and succeeding activities along with the respective details. The preceding activity needs to be scheduled based on "Backward Scheduling". The succeeding activities need to be scheduled based on the "Forward Scheduling".

The system displays the following in the “Bottleneck Sequence” multiline:

Work Order No.	The number identifying the work order for which scheduling is done.
Customer Name	The name of the customer.
Item Code	The code identifying the item for which scheduling is done.
Variant Code	The code or number identifying the variant of the item.
Desc.	The description in combination of item/item variant.
PP Seq.	The number identifying the sequence of the activity in the work order process plan
Activity Code	The code identifying the activity for which scheduling is done.
Activity Description	The description of the activity.
Activity Start	The start date/time of the activity.
Activity End	The end date/time of the activity.
Order Start Date	The start date of the work order.
Order Due Date	The end date of the work order.
Order Qty.	The quantity of the output item of the work order.
Status	The status of the work order.

Enter the following in the “Bottleneck Sequence” multiline:

Start By Date

The user-defined date on which the work orders are considered for scheduling. If for any specific activity in the multiline if this field is specified then the system starts the specified activity not earlier than the specified "Start By Date" and considers this date as start date for the specific activity. The system displays “Blank” by default on launch of the page.

To proceed, carry out the following

Select the “Sequencing Rule” link at the bottom of the page to specify the sequencing rule codes for the work orders.
Select the “Edit Work Order” link at the bottom of the page to modify the details of the selected work order.
