Hi everyone,

I'm looking for a method to edit the **StartTime** and **EndTime** of a historical **Production Run** using a Sepasoft MES script. The **MES Value Editor** allows changes by selecting different `tagCollectors` types, but I need a script-based approach for automation.

I found a reference script([Link](https://docs.sepasoft.com/articles/#!knowledge-base/how-to-change-dates-of-an-operation-after-production-run-3-0)) in the Sepasoft manual that modifies `newStartDate`, but it doesn’t provide an option to update the `endTime` accurately. I have a UI with the following fields:

- **WorkOrder**
- **Product Code**
- **StartDate**
- **EndDate**
- **Infeed**
- **Outfeed**
- **Reject**

My goal is to modify the **StartDate** and **EndDate** fields programmatically. Does anyone have a working script or an alternative method to achieve this?

Any help would be greatly appreciated!

Thanks!
