 Workflow for Check-in:
  * Lock appointment
  * Check if we can check-in the appointment in PIMS
- * Check-in the appointment 
+ * Check-in the appointment in BSDX APPOINTMENT (rollback: none needed on failure)
+ * Add check-in in file 44 (rollback: remove check-in in BSDX APPOINTMENT)
+ * Call event driver (point of no return)
+
+Rollback strategy: Single point of failure: reverse check-in at BSDX APPOINTMENT.
+
+M Error Handling: none. If the error occurs inside BSDXAPI, the same rollback activates and rolls back check-in in BSDX APPOINTMENT.
+
+Limitations of Rollback: If an M error occurs in BSDX25 after BSDX APPOINTMENT filing, it is not rolled back.
+
+Workflow for Remove Check-in:
+ * Lock appointment
+ * Check if check-in can be removed in PIMS
+ * Get old check-in date and save off in case of rollback.
+ * Remove check-in from BSDX APPOINTMENT (rollback: none needed on failure)
+ * Remove check-in from 44 (rollback: put check-in back into BSDX APPOINTMENT)
+ * Call event driver (point of no return)

+Rollback strategy: Single point of failure: reverse check-in at BSDX APPOINTMENT.
