Webservice with and temp Table

stony

Hello,
I have a page, which displays the Lot Numbers (as a list) to an article. This page gets the data via a function in the page, because the page has set the property SourceTableTemporary to Yes. The SourceTable is Lot Number by Bin Buffer.
The OnOpenPage trigger calls the local function FillTable, which inserts the data.
The article number is transferred with another function (ParameterSet) and this is then used in the FillTable.
This works inside Navision perfectly!

Now I want to use this page as a web service. How can I transfer the article number so that the Lot Numbers list is created only for this article number.

Thanks,
stony

Each web service call is a separate session, so remembering values global vars or single instance codeunits won't work. You have to pass the requested value in the same call which is supposed to retrieve the data.

The solution proposed by @allenyyzhou have all chances to work. First, try to make your "Article number" a flowfilter in your table. If it still doesn't work try moving the code and add some code in OnFind. Perhaps something like this

OnFind(Which : Text) 
ArticleNo := GETFILTER("Article number")
RESET; //may or may not be needed 
IF ISEMPTY TEN
  FillTable (ArticleNo);
EXIT(Which)

(Note I did not try this myself either )

Hi

Just an idea, you add this "article number" as a field into your source table.
Before you get data from the web service, you can set filter to "article number", and inside the page, you can Getfilter of "article number", then clear filter, insert data.

Where in the page I can read this filter and delete it again.

Hi

Sorry, I have not try this, but could you try in the OnOpenPage trigger?

Unfortunately does not work

I tried making this work the other day, but without luck. (Odata)
Couldn’t find a trigger that worked.
I solved it with the real table and som flow fields for the needed data.

So maybe we are stuck on soap and xml/codeunit for this scenario???
Or if you can compose a query instead.

Late to the party but perhaps helpful to the weary internet traveller:

Can confirm the suggested solution of @allenyyzhou works for NAV365 / 14.

If you create a page based on a temporary table, publish it as a webservice and require to fill it with a custom function you can pass variables to OnOpenPage as a filter in the ODATA query f.e.

http://nav365:7048/NAV/ODataV4/Company('CRONUS')/CustomCustomerPage?$filter=No eq '1005'

You can use GetFilter("No.") in the OnOpenPage to retrieve the filter (1005) value. Be sure to call Reset() as suggested to clear this and any other filters if you don't actually want them applied.

    trigger OnOpenPage()
    var
        Customer: record Customer;
    begin
        if (Customer.GET(GetFilter("No."))) then begin //Retrieve filter value
            Reset(); //Clear filters
            SetPageData(Customer."No."); //Call to the custom function to fill the temp table
        end;
    end;
