Hello, folks, I am New to Cloverleaf, what i would like to do is to covert csv record to hl7 outboud message by using VRL. What need to be configure to achieve

Our csv file coming like:

MRN1, Patientname1, DOB,Encounter#,Dignosisecode1,Code1decription1,

(cont at same line) diagnosisecode2,Code1decription2

Dignosisecode3,Code1decription3 …… (This varies, it can up to 25 or just one)

MRN2, Patientname2, DOB,Encounter#,Dignosisecode1,Code1decription1,

(cont at same line) diagnosisecode2,Code1decription2

Dignosisecode3,Code1decription3 …… (This varies, it can up to 25 or just one)

The outbound HL7 will be:

MSH..
