SQL Server Reporting Services error: The report parameter has a DefaultValue or a ValidValue that depends on the report parameter . Forward dependencies are not valid.

For an application we are using SQL Server Reporting Services. However we had issues with one report. In this report, we have 2 parameters, e.g. OrderId & CustomerId. The value for CustomerId is calculated by executing a first query using the OrderId parameter. This is something that can be done easily in reporting services. However after configuring the parameters, compilation failed with the following error message:

[rsInvalidReportParameterDependency] The report parameter ‘CustomerId’ has a DefaultValue or a ValidValue that depends on the report parameter “OrderId”. Forward dependencies are not valid.

 

Build complete -- 1 errors, 0 warnings

It sounds like a parameter can not depend on another parameter but why did they provided this functionality? Obviously there must be something else that we did wrong.

After trying almost everything you could imagine, we finally discovered that the order of the parameters are wrong. In the parameters list of your SQL Server Report it is important that you place the parameters in the correct order(!).

So after putting the OrderId first and the CustomerId second, everything worked…Verwarde emoticon

.NET 8–Keyed/Named Services

A feature that a lot of IoC container libraries support but that was missing in the default DI container provided by Microsoft is the support for Keyed or Named Services. This feature allows you to register the same type multiple times using different names, allowing you to resolve a specific instance based on the circumstances. Although there is some controversy if supporting this feature is a good idea or not, it certainly can be handy. To support this feature a new interface IKeyedServiceProvider got introduced in .NET 8 providing 2 new methods on our ServiceProvider instance: object? GetKeyedService(Type serviceType, object? serviceKey); object GetRequiredKeyedService(Type serviceType, object? serviceKey); To use it, we need to register our service using one of the new extension methods: Resolving the service can be done either through the FromKeyedServices attribute: or by injecting the IKeyedServiceProvider interface and calling the GetRequiredKeyedServic...

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
