The purpose of a modify message is to add data to, delete data from, or change data which is a part of a record. The modify violent gang/terrorist organization message must be made only by the agency that originally entered the record. To modify a record it must be identified by group name, and subgroup name. Group name and subgroup name must be exactly the same as it appears on the original entry, including spelling. These data items are used to identify the record to be modified, and as such they cannot be modified themselves.
Modifying changes the content of a record by substituting other data or adding new data to an established record. Deleting an item takes the item out of the record without substituting new data. . To delete data from an existing record, use the pound sign (#) in the field you wish to delete.
While both supplement and modify transactions may be used to add information to an already established missing person record; the supplement transaction is used to add information to a field that already has information in it. The modify transaction may be used to add information to a record when a field was left empty on the original entry transaction.
Any agency with pertinent information concerning the TTO, DRS, HND, GTI, or MIS Fields should contact the primary ORI/POC to request a modification of the record information when appropriate. Any ORI can modify its own ORI/POC data fields of a record. If any agency other than the primary ORI attempts to modify any field other than that agency’s own ORI and POC information, the transaction will be rejected.
