Hi Team,

We have migrated our v10.2.11 code to v11.3.1.

After that we have got below warning related with obsolete method.

**“ComplexDispatchAndTrackInInput.Recipe is obsolete:Use MaterialRecipeInformation instead”**

* * *

we have used “MaterialRecipeInformation” as stated but it is giving an error.

Could you please here. Your help would be appreciated.

Thanks,

Sandip Dhakane

Hi Sandip,

The **`ComplexDispatchAndTrackInInput.Recipe`** property was marked obsolete and replaced by **`MaterialRecipeInformation`**. This is a structural change to how recipe information is passed into the Dispatch & Track-In operation.

The key difference is that **`MaterialRecipeInformation`** is not a simple string/object replacement for the old **`Recipe`** property — it’s a dedicated class that wraps recipe-related data with its own structure.

Lookup the new class in the API reference to understand the new structure: [Host API | Host API - CM MES](https://developer.criticalmanufacturing.com/11.3/reference/api-host/index.html)

Regards
