The Customer Data Parser (CDP) will flag changes to the original data if the flag settings are enabled (FLAG_NAME_LINE_CHANGES, FLAG_STREET_LINE_CHANGES, and FLAG_GEOGRAPHY_LINE_CHANGES). The default is not to flag any changes. A change can be a recode from the definitions tables or the correction of a city name from the city table. As long as the value in the recoded attribute is different from the original attribute in the Parser Repository (PREPOS), it is considered a change.
The change flag will be stored in a section of attributes in the secondary Parser Repository (PREPOS2). This section of attributes will be divided into three sub-sections: street line changes, geography line changes, and name line changes. Each changed flag attribute corresponds to a pair of recoded and original attributes and is one character long. A value of '1' in a changed flag attribute indicates that an original attribute has changed. If there is no change, then the changed flag attribute will be blank.
The following is an example of a street type change:
pr_street_type1_original = ROAD
pr_street_type1_recoded = RD
pr_street_type1_changed = 1
The table given below lists the Parser Repository (PREPOS2) attributes to store change flags.
*Attributes pr_name_line_changed_flags_01 to pr_name_suffix_changed_01 are repeated 9 times, one for each of the other 9 name sections.
