Add attachments to Sales documents.
This is not a prerequisite if the user has sufficient authorization level.
But if the user has sufficient authorization and receives an error message(for example) -No service available
Message no. SGOS_MSG002
Then user can verify if the parameter Id SD_SWU_ACTIVE has value X in the user profile.
How to verify the user profile?
Select drop down menu System->User Profile-> Own data
Go to Parameter tab. Enter Parameter ID-SD_SWU_ACTIVE & Parameter value X.
For example: If it is required to attach document to sales order,Go to VA02 transaction code, use following menu path to create attachment:
System->"Services for Object"->Create Attachment
To view the attachments already attached use following menu path:
System->"Services for Object"->Attachment list
P.S - The menu path remains same in the respective transaction code to Change Sales Order/Delivery/Quotation/Inquiry/Billing Document.
