DCM generates a patients.in file that can be read in by Best Practice should you choose to use the BP instead of the DC Clinical Module. This will create new patient records in BP and update existing.
This needs to be setup in both DCM and BP.
In DCM go to Utilities - Configure - Intergrations and browse to the path where the patients.in file will save
In BP go to Setup - Configuration - Links and complete as per the following. Note the 'Run the data import process on this computer'. You need to ensure that BP is running on the computer with the Link setup. If not, detail will not transfer to BP
