Where can I set the sales rep field value to be mandatory on a sales order?

AI generated answer (using internal Slack threads):

To set the sales rep field value to be mandatory on a sales order, you can use either a workflow or a client script (CS script). If you choose to use a workflow, you can create a new workflow that applies to the Sales Order record type. In this workflow, you can add a state that checks if the sales rep field is filled in. If it's not, you can show a message to the user or prevent the record from being saved. If you choose to use a client script, you can write a script that checks if the sales rep field is filled in before the record is saved. If it's not, you can show a message to the user or prevent the record from being saved. Please note that if the sales rep field is a custom field, you can also make it mandatory by checking the 'mandatory' checkbox on the field setup. However, this will make it mandatory for all record types where it is used, not just sales orders. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
