Supply Function not getting triggered.

[Former Member]

Hi All,

I have created WD program with Parent and child node and wanted to use SUPPLY FUNCTION to get the details of the child node whenever

selection changes in Parent node. I have used the document found in wiki for supply function creation, but my program does not call the Supply

function created. Kindly guide.

Further details:

Program fetches the details of the parent node and displays it correctly. But no data displayed in child node. Even if i change the selection of the parent

node record, supply function not getting triggered.

Parent node:

Cardinality 0..n

Selection 0..1

Initialization Lead Selection X

Singleton -

Supply Function -

Child Node:

Cardinality 0..n

Selection 0..1

Initialization Lead Selection X

Singleton X

Supply Function GET_VBAP

Please guide me on why the Supply Function is not getting called.

Thanks.

Hi Padmashree,

In supply function GET_VBAP, use standard parameter parent_element to read new data for the child node. As the lead selection in the parent node changes, so too will the reference held by this parameter. The link Chandra gave has a great example that should help you.

Cheers,

Amy

Hi Padmashree,

Please refer http://help.sap.com/saphelp_nw73/helpdata/en/f1/177741adb7167de10000000a155106/content.htm

I guess your applcation is simmilar to one mentioned in the SAP help link. Check if you are getting parent node details in the supply function associated with child node etc.

Thanks,

Chandra
