How to check whether a field value is modified or not in DMN? I have an use case where i need to check whether the Date value is modified or not, by the user while performing a user task.

I want to implement it in DMN under the specific column. Kindly share your idea.

Hi @arunkumar,

I’m not sure if I understand your question correctly. I assume that

  1. you have a process variable of type ‘date’
  2. this variable can be change within the process
  3. you want to check if the variable is changed in a DMN decision table

Is this correct?

My first idea: create another variable which holds the initial value. In the decision table, you can simply compare if the values are equal (i.e. input entry: initialDate).

Does this help you?

Best regards,
Philipp

Thanks @Philipp_Ossler,
Yes, your assumption is correct. I got your idea too.
Meanwhile can we use not(initialDate) in DMN for same scenario?

Yes, you can use not(initialDate) to check if the given date is not equal to ‘initialDate’.
