Purchasing Integration of Customer specific Purchase Order Type from SAP CRM Campaign

Hi all,

we would like to use the SAP CRM standard assignment block "Purchase Goods / Services" of the Campaign Component in order to create purchase orders in ECC which are related to the Campaign.

Due to fact that I have not found any real configuration documentation / best practices I have the following questions:

1) Which is the configuration to be performed, e.g is there any customisng entry where I can maintain that a customer specifc purchase order type should be created. With regards to Middleware: any preparation steps to be performed.

2) Which BADIs can be used ?

3) A part from the rather process oriented description in the SAP Help - is there any config document.

Thanks for the help,

Bernhard
