Due date empty on the first MP generated

@Andryis  Please check whether the below information, clarifies you. Calculating Planned due dates requires at least two or more accumulated measurements in case of Performed Value Based = Yes.

If any cumulative criteria is registered, one condition line is shown on the Maintenance Plan tab even before any measurement is registered. You can manually generate work orders having this line only. When two or more accumulated measurements are registered, it generates a condition based forecast PM plan by calculating the average use per day under the assumption of linear use of the equipment object. When the condition generation routine is started, work orders will be generated if a recorded measurement falls outside the acceptable limits defined on the PM actions.

If accumulated condition-based PM action is set to Performed Value Based = Yes, the Planned Values of the maintenance plan will be recalculated and adjusted based on either.

• The Last Measurement at Maintenance, or
• The Predicted Value at Maintenance.

However, the Due (planned) dates will be predicted under the assumption of linear use of equipment.
