KB73059494: Automation Engine - Task fails with error "Could not register user - missing mark marker"

Summary

A task which tries to apply a smart mark set, fails and you get the following error messages:

ERROR: Mark marker not registered Removing mark.

ERROR: SmartMark set not applied

ERROR: Error while applying SmartMarks

could not register user - missing mark marker

This can happen in any task that:

• Has an option to apply smart marks.
• Is not a Step & Repeat task.

       E.g. FlexRip, FlexProof, Export to PDF, etc.

Symptoms

• Automation Engine tasks fail.
• The task log contains the errors mentioned above.

Solution

The smart mark set contains one or more marks which refer to Step & Repeat related information. 
E.g. A mark named Position Mark which uses a formula to calculate a position. This formula contains parameters such as:

• GridHeight1
• GridWidth1
• Gap1
• NumberOfGrids, etc.

Some parameters are only available when you create the smart mark set in Plato.
Smart mark sets with these kind of parameters, can only be used on Step & Repeat related tasks, such as:

• Import JDF Step & Repeat
• Step & Repeat CAD based
• Step & Repeat Tabular
• Step & Repeat Template based
