How to determine output based on the content of purchase order

Question

Hi Gurus,
I've a typical requirement at my present project. With vendor X we have punchout catalogs. while creation of shopping cart, we are not allowing the user to mix catalog items and non catalog items into the same shopping cart. Once the shopping cart all shopping carts are automatically coverted into PO.
Now the challenge we are facing is, if the PO is created based on items from catalog, we want to send such PO via XML interface to the vendor. If the PO is created based of items which are free-form, we want to send such PO via Smartform email attachment.
As this condition can only be determined at runtime, I'm finding a challenge to configure this. In both PO cases, vendor is same but the content of the PO is different. One contains all items that are catalog based and other contains items which are non catalog.
Can someone help me find solution for this issue.
Regards,
Sam K

Change Forms for Document Output
You can use the Business Add-In BBP_OUTPUT_CHANGE_SF to override the Smart Forms that are defined in the activity Define Actions for Document Output.
This BAdI serves as an alternative to the IMG activity Condition-Dependent Document Output.
Note that no Smart Forms are used for output via XML.
Standard settings
The following parameters are available in the method CHANGE_FORMS. Depending on the input parameters, you can define other Smart Forms to output the document type.
Importing
IV_GUID
Globally Unique Identifier of the document.
IV_MEDIUM
Output medium found for this document according to Define Actions for Document Output (print: PRN, fax: FAX, e-mail: MAI, XML: MET).
IS_PARTNER
Business partner to whom the document is sent.
IV_OBJECT_TYPE
Business transaction type.
Changing
CV_SMARTFORM
Smart Form used to output the document.
E-mail output
Smart Form with which the document is added to the e-mail in the form of a PDF attachment.
Note:
Note that the BAdI with this parameter overrides the parameter form name (technical name of the Smart Form BBP_PO for example) irrespective of the defined determination technology (SRM: Purchase Order Output Determination, for example).
CV_SMARTFORM_MAIL
Smart Form used to define content and layout of the e-mail text in the case of e-mail output.
CV_SUBJECT_MAIL
Smart Form that determines the text in the (short description of the e-mail content).
As an alternative to this BAdI, you can control document output via determination technology.
