SRHLVORU ;B'HAM ISC/DLR - Surgery Interface Receiver of ORU message ; [ 05/06/98   7:14 AM ]
 ;;3.0; Surgery ;**41**;24 Jun 93
 ; Per VHA Directive 10-93-142, this routine SHOULD NOT be modified.
 ;processing of incoming ORU message
 ; 1. process MSH - create field separator and other encoding characters
 ; 2. process PID - establish patient IEN
 ; 3. process OBR - create observation identifier and stuff fields
 ;    a. process OBX - using OBR identifier stuff fields
 ;    b. process NTE - using OBR identifier stuff anesthesia comment
 ; 4. use ^TMP("SRHL" global to create a descrepancy report if needed
 ;
 ;  Troubleshooting
 ; What to do if a field is not being added?
 ;  1. View descrepancy message.
 ;  2. Check the Flag Interface Fields option for a receive flag.
 ;  3. Check to see if the field has an input transform.
