When I try to customize the credit memo entry form, I am not able to set "Job" field as mandatory. Anyone knows how to make this field mandatory? This field is a dependent dropdown of the entity field.

Try SA31753

Thanks. Just found out that the credit memos in my case are being created automatically by scheduled scripts triggered when a payment is accepted for an invoice. So, I'm still trying to find how to "inherit" the project from the invoice to the credit memo.
