Primary Key Value - MFA
2003-08-22
Definition: This field uniquely identifies the record of the master file (identified in the MFI segment) for which the update status is being acknowledged (as defined by the field MFN-4 - Record Level Error Return). The data type of this field is defined by the value of MFA-6 - Value Type - MFA, and may take on the format of any of the HL7 data types defined in HL7 table 0355 - Primary Key Value Type. The PL data type is used only on location master transactions.
The following exception to the use of the CE data type is deprecated in V2.3.1, and left in for backward compatibility. When the CE data type is used, the first component of this CE data field carries an optional subcomponent, the application ID, that uniquely defines the application responsible for creating the primary key value. The application ID subcomponents can be used to guarantee uniqueness of the primary key across multiple applications.
