The only way to update the persisted dynamic process properties is through Edit Process Properties.
For example, you have a persisted dynamic process property defined in your process, and you would like to update the value for the future executions.
You will need to first deploy the process, then go to Atom Management -> Properties tab, click on the blue triangle right next to the process, select Edit Process Properties and enter the value for dynamic process property.
Note that the dynamic process property name here has to be the exact same as the one in your process, and it is case sensitive. Also, the data format needs to match the format defined in your dynamic process property:
You will only need to enter the value for dynamic process property once, and all the future executions will update the dynamic process property accordingly. You won’t need to update it manually for every run.
