Writing Updated Resource Data Back to MPP files

Aspose.Tasks for Java lets you update a Microsoft Project MPP file’s resource data and save it data back to the MPP file.

Writing Updated Resource Data back to the MPP file The code snippet in this article opens a source MPP file that has one resource. It then updates the data of the resource and adds several new resources. The steps involved in this activity are:

1. Create an instance of the Project Reader.
2. Read the source MPP file.
3. Add resources to the project.
4. Update existing resource data.
5. Save the project using the Project Writer.

The following piece of code demonstrates this by an example. The first code snippet shows the process code and is followed by method definitions.

// For complete examples and data files, please go to https://github.com/aspose-tasks/Aspose.Tasks-for-Java
// The path to the documents directory.
String dataDir = Utils.getDataDir(WriteUpdatedResourceData.class);

String file = dataDir + "SampleNewMPP.mpp"; // Test file with one rsc to
                                            // update
// File to write test project
String resultFile = dataDir + "OutputMPP.mpp";

Project project = new Project(file);
Resource rsc = project.getResources().add("Rsc");
rsc.set(Rsc.STANDARD_RATE, BigDecimal.valueOf(30));
rsc.set(Rsc.OVERTIME_RATE, BigDecimal.valueOf(45));
rsc.set(Rsc.GROUP, "Workgroup1");

project.save(resultFile, SaveFileFormat.MPP);
