4.0 Workday Calendar Setup

Workday calendar controls the scheduling of Work Orders (WIP Job). You can define the working days ON/OFF, Shifts etc. Calendar setup is global but you can attach separate calendar for each Inventory organization.

Once you complete setting up the calendar you must build it.

bom_calendar_setup1

Navigate to BOM responsibility -> Setup -> Calendars.

1 ) Enter the name of calendar

2 ) Enter the description of calendar

3 ) Enter calendar range i.e. start date and end date

4 ) Click on ‘Workday Pattern’ to se the workday pattern.

5 ) Enter the sequence to be followed, how many days off and how many days off. If your organization works from Monday to Friday and Saturday and Sunday are holidays, then choose calendar start date as Monday then set ‘5’ days ON and ‘2’ days OFF.

bom_calendar_setup2

Enter the description of sequence and close the window.

6 ) Click on ‘Shifts’ to enter working shift information

bom_calendar_setup3

7 ) Enter the shift number and description, click on ‘times’ to enter shift start and end times.

8 ) Click on Dates

bom_calendar_setup4

9 ) Click on any date to make it exception i.e. work day OFF if it ON and viceversa.

10 ) Alternately you can click on ‘Exception List’ to manually enter exception date or import existing exception template. Exception template holds the holidays etc that can be applied to a calendar.

11) Once you finish Save the calendar and Build the calendar (Tools -> Build).

4.1 Lead Time Overview

Lead times play an important role in supply chain planning and scheduling. Efficiency and agility of supply chain is dependent on accurate lead time information.

Lead time consists of two main elements, they are fixed lead time and variable lead time. Fixed lead time doesn’t change for an item and it is constant. Examples are setup may be same whether to manufacture one item or 100 items.

Variable lead time is proportional to either quantity or lot size. Examples are assembly time to assemble one item is 10hrs and 2 items are 20hrs, it is proportionate to quantity(size) of operation. Other example could be like painting operation in a batch mode and batch size is 100, if you paint one item or 100 items is in same 10hrs, if the size is of the batch is 101 then lead time becomes 20hrs as they need to start another batch.

4.2 Item Lead Time Attributes

Item lead time information is stored in item attributes. Lead times are always maintained in number of days, if it less than a day then it is divided by 24hrs.

Below are the different attributes/elements of item lead time.

Pre-processing lead time: Time required to release a purchased order for buy item and it is time required to release a work order for manufacturing

Processing lead time: Time required to manufacture an item for make items and it is time required to receive goods since purchase order is issued to Supplier. This time is defined for a lot size, if this time proportional to quantity then lot size can be ‘1’, if it is proportional to a batch/lot size then the same can be entered. Usually this lead time can be calculated for manufacturing/make items based on operations routing/resource information.

Post-processing lead time: For buy items this is the time required from the date of receiving to till onhand is available in inventory for consumption. Post processing lead time for manufacturing lead time aren’t considered, if you have any inspection/approval process after manufacturing then include in the routing. This time is manually entered/or loaded through conversion process from a flat file and it is calculated.

Lead Time Lot Size: This is the attribute information used for processing lead times.

Fixed Lead Time: Fixed lead time that is independent of quantity you manufacture. This lead time can be calculated automatically.

Variable Lead Time: This is the lead time that is dependent on order quantity.

Cumulative manufacturing lead time: Total time required to manufacture if all sub-assemblies/components required to manufacture are available on hand.

Total lead time: Total lead time calculated by adding fixed lead time and variable lead time (after multiplying with order quantity).

Cumulative total lead time: Total lead time required procure or manufacture all levels of an assembly.
