Hello, I’m new to Epicor and I need to use the MES customization tool to access the oprseq’s of a job and prevent a worker from moving onto the next operation if the previous one was not completed. My main trouble is finding a way to call on the table and look at the oprseq’s. Thank you.
I recommend a lot of education before proceeding.
Start with the Epicor Customization Guide, Epicor Ice Tool Guide and the Programmers Guide.

Once you have some understanding of the Epicor Architecture and such we’d be glad to help
For this particular problem you are going to want to write a BPM probably on Labor.StartActivity method.
