I've extended the PurchaseOrderConfirmationRequest report in D365 AX Visual Studio and extended the PrintMgtDocTypeHandler class to render the updated design instead of the original:
case PrintMgmtDocumentType::PurchaseOrderConfirmationRequest:
_result.result(ssrsReportStr(PurchPurchaseOrderExt, Report));
break;
This approach works for 5 other SSRS reports I've extended. Deploying reports works (no errors), and the other 5 reports render my updated design with no issue.
When it comes to this specific one though, it ALWAYS renders the original (default) SSRS design and not the one I created.
I have set up the Print Management section in Accounts Payable, setting the "Purchase order purchase inquiry" document to override the "Original" design with my custom design (PurchPurchaseOrderExt), yet it always renders the original (default) design whether I choose to preview from Original or Copy.
Are there any additional steps for Account Payable reports that I'm missing? All of my other 5 reports are Account Receivable reports and they work with no issue.
