Product Configuration: Performance with Z3


In the spring release of 2018 for Microsoft Dynamics 365 for Finance & Operations a significant investment in improving performance of the constraint evaluation has been made.

The result of this investment is the introduction of the Z3 sovler strategy. Z3 is a theorem prover from Microsoft Research, that has won several awards and has an active open source community.

The Microsoft Dynamics 365 for Finance & Operations team, teamed up with the Microsoft researches to develop new algorithms targeted at the Product configuration scenarios for Microsoft Dynamics 365 for Finance & Operations.

Microsoft Dynamics AX 2012 R3

The Z3 solver strategy is also available for Microsoft Dynamics AX 2012 R3 with the following KB article numbers:

  •  4046549 - Performance improvement of loading models
  •  4034024 - Fix to support customization related to system defined table constraints
  •  4012892 - Introduction of the Z3 Solver strategy


The applied solver strategy for a product configuration model is selected by accessing the Model properties form.

From the Model properties form the Z3 solver strategy can be selected as illustrated below:

The Z3 solver strategy will currently not have a functional impact, the impact will be on performance.
