The debtor role in a partner can have three different types - how do I use these types and what do they mean?
Types: Single debtor, Master, Child

Types
Single Debtor
Information is registered as a single, independent debtor
Master-Debtor
Information is registered as a master-debtor.
Acts as a single debtor as well, but can also be referenced as master from child debtors.
Child-Debtor
Selecting this option allows selecting a corresponding master debtor in the box below.
A child debtor has no own account number and always has to point to a master debtor.
Optional: Deviating payment terms from master.
Master/Child configuration is suitable for headquarter/branch constellations or central billing services. Master and child will have the same debtor account number and will have the same credit limit. The address on an outgoing invoice will come from the Invoice Recipient Partner used.
If the tax rules of both Partners are different (e.g. one is located in your own country and the other one is not), you should not use this functionality.
