通过ProjectEntry图/C#代码创建项目时模板任务未加载的问题

在Acumatica定制开发中，通过ProjectEntry图与PMProject DAC以C#代码创建项目后，发现模板关联的任务并未同步到新项目中。原代码如下：

//create the project graph...
ProjectEntry projentry = PXGraph.CreateInstance<ProjectEntry>();

PMProject pmproj = new PMProject();

//Set the ProjectID:
pmproj.ContractCD = "000001"; //Project preferences is set to allow manually created project CDs...

//The template ID...
var tmplt = (PMProject)PXSelect<PMProject, 
                       Where<PMProject.contractCD, Equal<Required<PMProject.contractCD>>>>.Select(Base, "00TEMPLATE01");

pmproj.TemplateID = tmplt.ContractID;

//The description....
pmproj.Description = "Test description";

//Now save the new project...
pmproj = projentry.Project.Insert(pmproj);                                
projentry.Persist();

Acumatica中仅设置TemplateID并保存项目，不会自动触发模板任务的复制逻辑，需要主动调用项目图中的对应方法。具体操作如下：

• 先插入并保存新项目，确保生成有效的ContractID
• 调用ProjectEntry图的CopyTemplateTasks方法，传入新项目的ContractID，完成模板任务的复制
• 再次执行持久化操作，将复制后的任务数据保存到数据库

修改后的完整代码示例：

//create the project graph...
ProjectEntry projentry = PXGraph.CreateInstance<ProjectEntry>();

PMProject pmproj = new PMProject();

//Set the ProjectID:
pmproj.ContractCD = "000001"; //Project preferences is set to allow manually created project CDs...

//The template ID...
var tmplt = (PMProject)PXSelect<PMProject, 
                       Where<PMProject.contractCD, Equal<Required<PMProject.contractCD>>>>.Select(Base, "00TEMPLATE01");

pmproj.TemplateID = tmplt.ContractID;

//The description....
pmproj.Description = "Test description";

//Insert and save the new project first to generate valid ContractID
pmproj = projentry.Project.Insert(pmproj);                                
projentry.Persist();

//Copy tasks from the specified template to the new project
projentry.CopyTemplateTasks(pmproj.ContractID);

//Persist the copied task data
projentry.Persist();

• 确认目标模板项目（00TEMPLATE01）本身包含可复制的有效任务，且模板状态允许被复用
• 确保新项目处于可接受任务的状态（如Active），避免状态限制导致任务复制失败
