Reopen a Purchase Order to update via API v2

Posted on by VTRAN

Hi, I have no experience with Dynamics 365 Business Central. I'm building a Purchase Order integration from an external application to D365.

It appears to me to update an existing Purchase Order, it needs to be reopened. But, I haven't found a way to reopen a PO using the standard API.

If I tried using the Update PO request to set the status field to "Open" resulted in an error "Control 'status' is read-only".

I do not have access and the D365 skills to develop a custom API. Is there a way to reopen a PO using the standard API v2? If not, is there a workaround?

Hello,

Editable property of Status field is false in "APIV2 - Purchase Orders" , that's why it can't be modified through patch request. A custom API can be developed.

Hello,

You should not edit the ‘Status’ field directly, as it may cause downstream issues such as workflow, prepayment etc.

You can use Codeunit "Release Purchase Document" to change the field status.

ReleasePurchaseDocument.PerformManualReopen(Rec);

ReleasePurchaseDocument.PerformManualRelease(Rec);

@Yi Yong: I don't understand what it means "Codeunit Release Purchase Document"? Did you mean developing some custom code to call this function? or can it be executed via the API?

It sounds like this simple action with a standard API is impossible, and custom code/API is the way to go. Thank you all for the answers.

Hello VTRAN,

Codeunit Release Purchase Document is a standard codeunit, you need to call this codeunit and run the respective function to set the status of the purchase document.

trigger OnAfterGetRecord()
var
ReleasePurchaseDocument: Codeunit "Release Purchase Document";
begin
ReleasePurchaseDocument.PerformManualRelease(Rec);
end;
