Please advice, if this can be done.

I guess that you are using a Enslib.HL7.Service that uses EnsLib.File.InboundAdapter as Adapter. The problem is that the name of the file is not a property of Enslib.HL7.Message class, so you have to follow these steps:

Create your own service that extends to Enslib.HL7.Service.

Overwritte OnProcessInput process to get the name of the readed stream:

Set tFileName=pInput.Attributes("Filename")
set sessionID = $$$JobSessionId
set ^GlobalName("Session", sessionID) = tFileName
do ##super()

From DTL use code to get the global that you created before getting the ID session from Enslib.HL7.Message and assign it to MSH property:

Set globalValue = $GET(^GlobalName("Session", sessionID))

And finally assign globalValue variable to the MSH propery (using SET from the DTL):
```
target.{MSH.PropertyName} = globalValue
```

Yes, filename capture during a Business Process (BPL) process and setting it to MSH-6 in an HL7 message can be performed as described below:

Access the Original Filename: To access the original filename in BPL, you can use the property request.OriginalFilename if the message contains the Ens.StreamContainer object, which holds metadata like the original filename [1].
Modify the HL7 Message: Using a DTL transformation within the BPL, you can set the value of MSH-6 in the HL7 message to the retrieved filename:
- Create a Data Transformation (DTL) that modifies the HL7 message.
- Use the context variable or the filename in the source (e.g., context.Filename) and assign it to the corresponding field target.{MSH:6} in the target HL7 structure [2][3].
Sequence of Actions:
- Retrieve the filename from the incoming data and store it in a context variable within the BPL.
- Pass the HL7 message and the context variable to the DTL.
- The DTL should include logic to map the context variable (e.g., context.Filename) to target.{MSH:6}.
