Supply function.

[Former Member]

Hi all,

I have table contains flight details ,

data source context is NODE_FLIGHT_DETAILS.

In that i have written supply function PUT_VALUES_TO_NODE_FLIGHT_BOOK, it's purpose is to

fill another context NODE_FLIGHT_BOOK on every row selection of table.

but it's not working on every row selection of table ...

I have done it as such as in wdt_master_detail example in SWDP_DEMO_TUTORIALS... here they have written supply function s_spfli for context spfli.. and it;s working but ...mine is not working ....i am not getting what exactly happend ??

anyone have any idea ???

Regards

HI Jose,

Using First supply function fill your table.

Then go to the Table properties-> OnleadSelect -> Create one event Handler.

Then Get the selected Data from the table and then Based on the Selected value fill the second context NODE_FLIGHT_BOOK .

So when ever the Row selectd in the table, It will be avilable in NODE_FLIGHT_BOOK.

Thanks.

Hi Jose,

Supply functions are used to fill the context node to which they have been bound. Here you have assigned the supply function to PUT_VALUES_TO_NODE_FLIGHT_BOOK to context node NODE_FLIGHT_DETAILS and want to fill another context node NODE_FLIGHT_BOOK.

If this is so, you should proceed as follows:

1) The context node NODE_FLIGHT_DETAILS must be a singleton node, and must act as the parent node for context NODE_FLIGHT_BOOK (nesting of nodes).

2)Next assign the supply function PUT_VALUES_TO_NODE_FLIGHT_BOOK to node NODE_FLIGHT_BOOK .

3) Implement the supply function to fill values in NODE_FLIGHT_BOOK based on the row selected in NODE_FLIGHT_DETAILS.

You have two parameters in any supply function:

NODE

PARENT_ELEMENT

Using PARENT_ELEMENT, reference the current row of the parent node and use NODE to populate the child node based on the value in the parent node.
