Access Formulas in Runtime

Customized formula file can only be accessed under the latest RuntimeFormulas\<recipeid>\<recipeid recipeversion> folder.

The following describes a typical scenario of how you can use the formula in Runtime.

• You have a recipe called SkinCream, which has a version number 3.

• The SkinCream recipe is approved by you in the AVEVA Batch Management system. The RuntimeFormulas\SkinCream\SkinCream v3 folder is created automatically.

• You select the SkinCream recipe and then export its formula to a file called SkinCream.csv under the Config_A folder.

• You modify the exported file and save the modified file as SkinCream Light.csv and SkinCream Regular.csv.

• In order to access these modified files under the runtime, you must copy these files under the RuntimeFormulas\SkinCream\SkinCream v3 folder.

• In the Batch Scheduler window, you select the recipe SkinCream and then click the Formulas button. The SkinCream Light and SkinCream Regular formulas will be shown in the dialog. You can select this formula to override the formula values in the recipe.

• Later on, you modify the recipe and save it, which has a newer version. When approved, a new directory called RuntimeFormulas\SkinCream\SkinCream v4 is created.

• Assume that the modified files are still valid for SkinCream version 4, you must copy the files SkinCream Light.csv and SkinCream Regular.csv to the directory RuntimeFormulas\SkinCream\SkinCream v4. If the formulas are not valid anymore, errors will be displayed when you try to initialize the batch. In this case, you should export formula from SkinCream again, and customize the newly exported file.
