Dynamics NAV 2013 R2 OData

Hi,

I'm trying to call the page 5404 ("Item Units of Measure") through a web service. Whenever I'll open it I'll get this error "The Item does not exist. Identification fields and values: No.=''". Same error occours when I run this page from within C/Side.

The reason for this is this line:

  OnOpenPage()
  Item.GET("Item No.");When I call this page through the OData service Rec.Fields."Item No." is unset.

Question now is: How to set it from an OData call?

Thanks for your help,

Jörg

Are you filtering on specific Item when calling the OData?

Hi,

I'm trying to query the data like this;

var iUsoM = from iUoM in this.Nav.ItemUnitsOfMeasure
                   select iUoM;

Another try Fails as well:

var iUsoM = from iUoM in this.Nav.ItemUnitsOfMeasure
                   where iUoM.Item_No = "1001"
                   select iUoM;

Both results are the same.
The Problem is that Rec.Fields."Item No." is not set and this is used in OnOpenPage().
First line does Item.GET("Item No.");. This Fails.

So, how to set Rec.Fields."Item No." from an OData request?

Kind Regards
Jörg

Hi

If the page is note being called by a valid "Item Unit of Measure" record then the "Item No." will be blank in OnOpenPage trigger.
Try to move your Item.GET code to OnAfterGetRecord trigger and change if to

IF NOT Item.GET(...) THEN
Item.INIT;

It is correct that not all pages can be exposed succesfully as an OData feed. This is especially true if the page requires a certain context to run.
In those cases you will have to either refactor the page or create a dedicated codeunit/page/xmlport or Query that you can expose.

Howdy, Stranger!
