Difference between Synchronous & ASynchronous.

Hi All,

I few queries:

1) Difference between Synchronous & ASynchronous communication?

2) How should we decide whether it is a Sync or Async scenario?

Synchronous communication is typically used in the following application scenarios:

Sales and Distribution

· Creating a sales order in a different system (central sales).

· Performing an availability check for a particular material in response to an inquiry in the vendor system.

Asynchronous communication is typically used in the following application scenarios:

Materials Management/Sales and Distribution

· Sending business application documents to a vendor (for example, purchase orders, forecast delivery schedules, contract release orders), and ensuring that these application documents are only posted once in the target system.
