Which message or transaction key is used to enter protective order supplemental data?

The correct answer is based on the specific terminology and coding used within the legal and law enforcement context regarding protective orders. The keys ENPO and ENPT are designated for entering and processing non-restraining or temporary protective order data within systems that manage legal transactions.

When entering supplemental information about protective orders, it is crucial to use the designated keys that align with the data structure within the legal framework. ENPO refers to entering protective orders, while ENPT is typically used for transactions involving protective order updates or modifications. This indicates that the codes have been specifically designed to denote the actions related to protective orders and are recognized by law enforcement and legal practitioners.

In contrast, the other options (POPR/POPT, PRTR/PRPT, EPOD/EPCT) refer to different types of data transactions or codes that are not specifically tailored to the supplemental data of protective orders. Each of these codes pertains to different transactions or data types, highlighting why they are not applicable to this specific inquiry regarding protective order supplemental data.
