We can read the compressed format. Nightly all FROI datasets load first, then all SROI datasets. We do not require an IP to accompany a first report transmission. We have keyed IP information into our database from the paper WC13 forms for many years, so insurers do not have to send an electronic IP before an FN or S1. If it's not found, we will reject the transmission with a fatal error.
Electronic acknowledgments are in production.
We use the commission claim number, if present. The insurer may send the IP before the acknowledgment arrives, so the SSN will always be used as one method of finding a claim if there is no commission claim number sent. All other codes in these fields will be ignored for the time being. If we already have IP information, we will count the transmission as a duplicate. For FN or SI transmissions, we will accept one period of TTD only.
