DeriveDocumentNumber
With this function you can derive CRF document numbers from the key fields entered in the Log-In form and the Batch Data Load program. If you modify this function, you must review the argument list, reapply the modifications, then reinstall the package. Inputs are:
- Key fields from the CRF and their ID numbers: Study, Clinical_Study_ID, Patient, Patient_Position_ID, Investigator, Investigator_ID, Site, Site_ID, DCI, DCI_ID, Event, Clin_Plan_Eve_ID, and Subevent
- Indicator of test or production mode date: RXC_ENV_TYPE
The function returns NULL if the derivation is not possible; otherwise it returns the derived document number. Document numbers generated by this procedure are not validated against the ValidateDocument function; they are assumed to be valid.
