AI Summary

  • The article discusses the importance of leveraging data contracts with attributes in Dynamics 365 Finance and Operations (D365FO) for defining parameters in the SysOperation framework.
  • Accessing attribute names dynamically, especially those decorated with custom names using [DataMemberAttribute], can be a challenge in D365FO.
  • X++ doesn't provide a built-in way to dynamically iterate through and access custom attribute names, leading to hard-coded solutions prone to errors.
  • The solution to this challenge involves using .NET reflection with CLR interop to dynamically retrieve custom attribute names in X++.
  • The step-by-step solution involves defining the data contract, using CLR interop to access reflection classes, and dynamically extracting custom attribute names.
  • The provided X++ code example demonstrates how to convert a contract object to a map by utilizing reflection to access property metadata.
  • Key points include dynamic attribute access, the use of .NET reflection for flexibility, and handling missing or null values in attribute names.
  • The benefits of this approach include maintainability, flexibility, and simplicity in working with data contracts in D365FO.
