Creating or Extending Shop Calendar in Dynamics NAV
One of the most frequent requests we receive is with regard to the error message that is received when trying to create a Production Order. The error message looks similar to the error message below:
Figure 1 – Error Message
The message is communicating that it is trying to calculate the start date for the order, but could not find a shop calendar (also known as capacity calendar) going back far enough to know what capacity is available in the work center. If the order has been backward scheduled, then the error message will say “When calculating Backward.” If the error happened as a result of using forward scheduling, then the message will say “When calculating forward.”
The fix to this message is to calculate the capacity for the work center so that the system can calculate the number of days required to produce the production order. The information below walks you through the process of creating/extending the shop calendar for a work center.
To create or extend the shop calendar:
- Go to the Work Center card for the work center involved.
