This would be a customization.

You can use an event handler for RowPersisting to check if there is at least one salesperson listed and throw an error if their is not.

[PXDefault(typeof(SOOrder.salesPersonID), PersistingCheck = PXPersistingCheck.Nothing)]

For the SOLine you can just modify the PXDefault Attribute to set the PXPersitingCheck to NullOrBlank which will make it a required field.

Hi @pandachan48   As suggested by @markusray17 It requires a small piece of customization.

Please find the code below.

// Sales Orders screen Customization 

public class SOOrderEntryExt : PXGraphExtension<SOOrderEntry>
#region SalesPersonID
[PXMergeAttributes(Method = MergeMethod.Append)]
[PXDefault(typeof(SOOrder.salesPersonID), PersistingCheck = PXPersistingCheck.NullOrBlank)]
protected virtual void SOLine_SalesPersonID_CacheAttached(PXCache cache)

// Customers screen Customization

public class CustomerMaintExt : PXGraphExtension<CustomerMaint>
public delegate void PersistDelegate();
public void Persist(PersistDelegate del)
if (Base.SalesPersons.Select().FirstTableItems.ToList().Count == 0)
throw new PXException("Salesperson info not found");
