Explanation of the error
You may come across this Salesforce validation error when deploying WaveRecipe metadata to your target org - "A Recipe must specify a Dataflow".
An example of the error message below:
This error is likely to be because you've not included in your deployment package a WaveDataflow component that is referenced within the WaveRecipe metadata.
Resolution
This is a known issue to Salesforce, and they have documentation available with explanation of the error and steps to resolve it.
To make sure your validation doesn't fail, on below example we're seeing both WaveRecipe metadata component (highlighted in blue) that requires its corresponding WaveDataflow component (highlighted in red) for a successful deployment.
This means that both of these components need to be added to the deployment package.
This guidance is in line with Salesforce's explanation confirming that:
"since every recipe has its own dataflow, including the dataflow alongside the recipe is needed to properly deploy recipes via change sets or packages.".
