Read and Write Rate Scale for Resource Assignments in Aspose.Tasks

Introduction

In this tutorial, we’ll delve into managing resource assignments rate scale using Aspose.Tasks for Java, a robust library for working with Microsoft Project files programmatically. By following these steps, you’ll be able to effectively manipulate rate scale settings for resource assignments in your Java applications.

Prerequisites

Before we begin, ensure you have the following prerequisites:

1. Java Development Environment: Make sure you have Java Development Kit (JDK) installed on your system.
2. Aspose.Tasks for Java Library: Download and install the Aspose.Tasks for Java library from here.

Import Packages

First, you need to import the necessary packages to work with Aspose.Tasks functionalities.

import com.aspose.tasks.Asn;
import com.aspose.tasks.Project;
import com.aspose.tasks.RateScaleType;
import com.aspose.tasks.Resource;
import com.aspose.tasks.ResourceAssignment;
import com.aspose.tasks.ResourceType;
import com.aspose.tasks.Rsc;
import com.aspose.tasks.SaveFileFormat;
import com.aspose.tasks.Task;
import java.io.IOException;

Step 1: Set up your project

Start by setting up your Java project and include the Aspose.Tasks library in your dependencies.

Step 2: Load the Project File

Load the Project file you want to work with into your Java application.

String dataDir = "Your Data Directory";
Project project = new Project(dataDir + "New project 2013.mpp");

Step 3: Add a Task

Add a new task to your project.

Task task = project.getRootTask().getChildren().add("t1");

Step 4: Define Resources

Define material and non-material resources and specify their types.

Resource materialResource = project.getResources().add("materialResource");
materialResource.set(Rsc.TYPE, ResourceType.Material);
Resource nonMaterialResource = project.getResources().add("nonMaterialResource");
nonMaterialResource.set(Rsc.TYPE, ResourceType.Work);

Step 5: Assign Resources to Task

Assign the previously defined resources to the task along with their rate scale types.

ResourceAssignment materialResourceAssignment = project.getResourceAssignments().add(task, materialResource);
materialResourceAssignment.set(Asn.RATE_SCALE, RateScaleType.Week);
ResourceAssignment nonMaterialResourceAssignment = project.getResourceAssignments().add(task, nonMaterialResource);
nonMaterialResourceAssignment.set(Asn.RATE_SCALE, RateScaleType.Week);

Step 6: Save the Project

Save the project with the modified resource assignments.

project.save("output.mpp", SaveFileFormat.Mpp);

Step 7: Retrieve Resource Assignments

Reload the saved project and retrieve resource assignments to verify the rate scale settings.

Project resavedProject = new Project("output.mpp");
ResourceAssignment resavedMaterialResourceAssignment = resavedProject.getResourceAssignments().getByUid(1);
System.out.println(resavedMaterialResourceAssignment.get(Asn.RATE_SCALE));
ResourceAssignment resavedNonMaterialResourceAssignment = resavedProject.getResourceAssignments().getByUid(2);

Conclusion

Managing resource assignments rate scale in Aspose.Tasks for Java is crucial for effective project management. By following this step-by-step guide, you can seamlessly manipulate rate scale settings for resource assignments in your Java applications.
