Optimization Tips

Large data and ModelFormulaContext

Do not store large data in ModelFormulaContext – this is because it is stored as an XML on the Optimization Model.

Do not to run an Optimization logic in the Debug mode

In general, it is not recommended to run an Optimization logic in the Debug mode. It is usually better to create a model, assign the logic to that model and run the logic directly from the model using the Calculate button on each calculation tab.

Create and Run Optimization Model Logic

Running a model for the first time

Before running a model with a single-logic configuration for the first time, you need to open the model’s Data Load of the type Model Calculation (it is created automatically when the model is saved) and uncheck the Allow distributed calculation checkbox. Otherwise you will get an error: “Formula for calculation phase not found”.

Create and Run Optimization Model Logic

Null values in segmentation dimensions

Avoid null values in segmentation dimensions. If necessary, create a new field by using an expression which replaces empty values by a text like “Not provided”.

Model evaluation on line item level

Be aware that running model evaluation on the line item level can negatively impact performance. Each model run may add 0.5-1sec for every line item, which results in quote being recalculated for e.g. 30 seconds or more. This may not meet the end users’ expectations when it comes to application performance.

Name field rules

Name field in Model Class must not contain any white spaces. It can only consist of alphanumeric characters or dashes

Model Class (MC)

Model name length limitation

For a model name, there is a limit of 50 characters. (This limit is valid for all FC uniqueName values in Pricefx and it originates from the limit of 63 characters in the underlying Postgres database.)

Set heartbeat

It is recommended to set your partition's heartbeat to a low value (20 s).
