Topic: Problem with slicing

view this post on Zulip Michael Sauer (May 11 2020 at 18:48):

I try to do some slicing using fsh:

In the example I use:

  • serviceCategory[Funktionsbereich].coding.code = #757
  • serviceCategory[Funktionsbereich].text = "Chirurgie CT"

sushi compliles this with no error.
The quality-report from IG-Publisher said:

Appointment/Patiententermin: Appointment.serviceCategory[0] (l10/c6) error Nicht unterstützter fixed Pattern Type für Diskriminator(coding.system) für Slice Appointment.serviceCategory:Kostenstelle: org.hl7.fhir.r5.model.UriType
Appointment/Patiententermin: Appointment.serviceCategory[1] (l19/c6) error Nicht unterstützter fixed Pattern Type für Diskriminator(coding.system) für Slice Appointment.serviceCategory:Kostenstelle: org.hl7.fhir.r5.model.UriType
Appointment/Patiententermin: Appointment.serviceCategory[0] (l10/c6) error Nicht unterstützter fixed Pattern Type für Diskriminator(coding.system) für Slice Appointment.serviceCategory:Funktionsbereich: org.hl7.fhir.r5.model.UriType
Appointment/Patiententermin: Appointment.serviceCategory[1] (l19/c6) error Nicht unterstützter fixed Pattern Type für Diskriminator(coding.system) für Slice Appointment.serviceCategory:Funktionsbereich: org.hl7.fhir.r5.model.UriType
<<<<

I don't have any more idea, where's the problem. Can anybody help me?

Thank you very much!

Michael

you could try:

serviceCategory[Kostenstelle].coding.system = "http://fhir.uniklinik-freiburg.de/ig/appointment/CodeSystem/UkfKostenstellenCS" (exactly)

I had a similar problem with valueCoding (if I'm reading your issue correctly) where I couldn't define a fixed system for the slice, but looking at other implementations that did similar, they actually had a binding to a valueset and only included codes from the one system in the valueset.
I don't know if that would work for your usecase but it worked for me.

@David Hay didn't work. I tried this before.

I think the problem is maybe, that coding is 0..* in serviceCategory

@ryan moehrke In my case, I need different value sets depending from the system. So that wouldn't help. Thank you for the idea.

Based on the error message from the IG Publisher, it seems like this could be related to some of the issues users were having in this thread: https://chat.fhir.org/#narrow/stream/179252-IG-creation/topic/New.20validation.20error.20.22Unsupported.20fixed.20pattern.20type.2E.2E.2E.22.

Some pattern types are not supported by the IG Publisher, and perhaps uri is one of those types? This seems to be the issue, but I'm not totally sure, because if this is what is causing your issue, I would have expected the solution suggested by @David Hay to work. Is there a similar error from the IG Publisher when the (exactly) keyword is used? Or is there an error from SUSHI in that case?

How about: serviceCategory ^slicing.discriminator.path = "coding.system" => serviceCategory ^slicing.discriminator.path = "system"

and does changing the discriminator type to 'pattern' help?

I had the same problem with all my slicing and solved as David says by adding (exactly) at every fixed system.

Thank you all for your support! All together you brougth me on the right way.
I had mixed up some things:

serviceCategory[Kostenstelle].coding.system = "http://fhir.uniklinik-freiburg.de/ig/appointment/CodeSystem/UkfKostenstellenCS" (exactly)

worked with ig-publisher. I had tested it with SMILE-CDR and there it doesn't work.
But with the advice of Nick I changed the type of from "uri" to "string" and: now it works! :-)
