Task: Create Receiver Variable Instructions (AiFunctionType.CreateRecieverVariableInstructions)

Turns receiver variable requirements into explicit variable-step instructions.

---

Use when

• you need clean variable instructions before action-object generation
• receiver stage needs reusable/preprocessed values for later senders/filters

---

Output contract

• plain instruction text for AiReceiverActivity.VariableTransformers[i].Instruction
• no JSON wrapper

---

Instruction input template (copy/paste)

Create receiver variable-transformer instruction text.

Message type:
- ...

Receiver input sample/template:
- ...

Required variable outcomes:
- ...

Constraints:
- variable setting only
- no destination mapping
- use explicit lines like ${VariableName} from SourcePath

Return only instruction text.

Example 1 (HL7)

Input

Extract message code and patient demographics for downstream sender filters/mapping.

Output

Set Variables:
  ${MessageCode} from MSH-9.1
  ${MessageTrigger} from MSH-9.2
  ${PatientID} from PID-3.1
  ${LastName} from PID-5.1
  ${FirstName} from PID-5.2
  ${DOB} from PID-7.1 with Format.Date(yyyy-MM-dd)

Example 2 (JSON)

Input

Extract patient and encounter identifiers from inbound JSON.

Output

Set Variables:
  ${PatientID} from patient/id
  ${EncounterID} from encounter/id
  ${FacilityCode} from encounter/facility/code

Example 3 (CSV)

Input

Columns: [0]=OrderId, [1]=PatientId, [2]=TestCode.

Output

Set Variables:
  ${OrderID} from [0]
  ${PatientID} from [1]
  ${TestCode} from [2]

Common failure modes

• including map/update instructions in this phase
• ambiguous variable names
• missing source paths
