Capable To Promise (CTP)

Key Concepts

PlanetTogether's Capable to Promise feature allows schedulers to input an item number for a finished good and delivery date to see whether or not the demand can be fulfilled within the given time frame. The system looks at available material and capacity to create a simulated job with a specified start and finish date. If the requested delivery date cannot be met, PlanetTogether will provide a realistic delivery date. 

Note: The key data points that will be required to submit a CTP request are:

  • Inventory (Warehouse + Item)
  • Required Quantity
  • Need Date
  • Required Path ID (the routing used to create the item)

Once a CTP has been submitted, PlanetTogether will project a Start and Finish Date/Time and display whether the job is expected to be late, on-time, early, etc. If the job is projected to be late, PlanetTogether will determine which constraints are causing the job to be late.

The CTP dialog can be accessed from the ribbon found at the top of the screen. Clicking the CTP button will open the following dialog: 

CTP Options

Naming the CTP

  • CTP Name: This is an identifier for the CTP job to be created. This is particularly helpful if the option to reserve capacity & material until the option is used.
  • Description: This is a description of the job to be simulated.
  • Customer: This is the identification of the customer for which the job is being simulated.


  • Inventory Inquiry: This can be used to check the inventory levels for the particular product to be produced. 
  • Reserve Capacity and Materials until This option allows the CTP to reserve capacity and materials until a user-defined date, allowing the customer to have some time to determine whether to go through with the order. In addition, this option allows the CTP to be dropped onto the Gantt to display when the capacity would be available for use.
  • Scheduling Type
    • Optimize: This option will run an optimize after creating the CTP.
    • Expedite to Clock: This option will expedite the job to the current clock to do the job ASAP.
    • Expedite to JIT: Expedites the job to its JIT Start Date. 

Product Availability: This tab allows users to select the item, quantity, and need data to be reserved for the simulated job.

  • Warehouse: This is the warehouse that CTP can draw materials from.
  • Item: This is the item to be produced. The item must have a template job with this item as a product to appear in the drop-down menu.
  • Required Quantity: This is the required quantity of items to be produced for the simulated job.
  • Need Date: This is when the simulated job would need to be finished.
  • Required Path ID: This is the routing to be used for the CTP. Every job will have one Alternate Path, but if there is more than one, all will be displayed in the CTP.

Once these elements are in place, the Capable To Promise can be saved by clicking Submit. Submitting the CTP will display the Scheduled Start and Finish Date and the result of the CTP (if the job is projected to be late, on time, early, etc.)


Priority: The priority tab allows the user to control additional aspects of how the CTP might be scheduled by allowing users to define:

  • Revenue: This is the revenue that the CTP would generate should the job go through. This value can be used in the optimize rules if higher revenue values are given more weight.
  • Throughput: This number can be used in optimize rules where higher throughput values are scheduled earlier.
  • Priority: This number can be used in optimize rules where lower numbers have a higher scheduling priority. 
  • Hot: This will flag the CTP as a Hot Job and take effect if there are optimized rules to prioritize hot flags.
  • Hot Reason: This is the reason that the CTP is defined as Hot. 

Warehouses: This tab allows users to define which warehouses CTP can draw materials from.

  • This tab lists all available warehouses, their Name, Description, and whether it is eligible to supply the CTP.
  • The drop-down menu has the following options:
    • Individual materials must come from the same Warehouse: All materials supplying the CTP must come from the same warehouse if this option is chosen.
    • Individual materials can come from multiple Warehouses: In this option, the materials requirements of the CTP can be supplied from multiple warehouses is required.

Bottleneck Constraints:

When the CTP is submitted, constraints that may make the operations late will appear here. Thus, schedulers can quickly see the details of the operation and the number of late days. In addition, listing the bottleneck constraints in this tab allows schedulers to easily identify the bottleneck operations causing the job to be late and see whether the schedule can be changed to produce the item(s) on time.
