Duplicate change task created on copy change

[ajay shrivas]

Hi All,

When I am clicking on copy change and submit the change request ,Duplicate change task are created .When I click on copy change again in the change request for which duplicate task are created .Again duplicate task are created in addition of earlier. There is no duplicate activity for task creation in workflow .  could you please suggest me on this.

This below article I already gone through, but still not gettng solution .

Any change task created from a workflow SHOULD have the field 'created from' populated with 'Workflow'. Any manually created tasks should not have that field populated. Tasks that are not created from = workflow are copied when you use copy change.

Thankyou in advance

Please share your 'copy change' code so we can see what is happening.

Again: please share your 'copy change' code so we can see what is happening. A screenshot to show the result doesn't give us any information on how that result got to be.
