STORAGE-SCP AE can be configured to apply a default value if​

there is no value specified.​

Value is saved to database as separate first and last names. Only​

first and last names are entered in the​

EXAMPLE-QUERY-RETRIEVE-SERVERdatabase.Bothfirstand​

last names can be a maximum of 64 characters each.​

Names will be parsed correctly if they are in the format of​

'lname^fname' or 'lname, fname'. If space separation is used (i.e.,​

'lname fname') then the entire name will be treated as the last​

name.​

Verification on incoming Patient IDs is performed. If an ID already​
