Update with join not working

Hello,

I created a job to fix a data issue by getting the correct value from a view that had been modified but it's not doing the update.  Please let me know if you can tell what I'm doing wrong.

Thank you

void

XTRA_Update_Asset_Departments(Args _args)

{

XTRAAssetMonthlyReport XTRAAssetMonthlyReport;

XTRA_AssetDimensions XTRA_AssetDimensions;

XTRAAssetMonthlyReport

XTRA_AssetDimensions

XTRAAssetMonthlyReport.AssetId == XTRA_AssetDimensions.AssetId

{

;

(XTRAAssetMonthlyReport.DepartmentId != XTRA_AssetDimensions.DepartmentId)

{

+ XTRAAssetMonthlyReport.AssetId);

XTRAAssetMonthlyReport.DepartmentId = XTRA_AssetDimensions.DepartmentId;

}

XTRAAssetMonthlyReport.update();

;
