The Scenarion is as follows...
A company provides the material to its customer whereas some of the material which it does not manufactures they ask their vendor to directly deliver it to the customer.
So.When i create a sales order i enter material for which i send...so system determines the item category and etc.
Whereas for the materail which is send by the vendor i just enter only text in the material description field the system determines the item category and schedule line category but it does noy create a purchase requisition.
Could any one guide of creating Purchase Requisition for the text.
