I really hope someone can help me with this one. My client creates purchase requisitions from an external system that interfaces into SAP. In SAP there is functionality to attach documents to a purchase req by choosing "Services for object". However, the client now has a new requirement that they want to upload and attach certain documents to the purchase req from their external system through a web service.
Is this possible? If not, is there another way they can upload the document to SAP? I stumbled upon the following web service: ECC_DOCUMENTCRTRC1. I have not been able to find any documentation on this web service. Can I use this web service for my requirement? If not, what does this web service do and does anyone maybe have some example code where this service is used?
