You need to transfer external data if you previously stored your data in non-SAP systems or in an SAP R/2 system, and now want to transfer it to the ERP system (such as to Cost Center Accounting). For example, you can transfer your planned primary costs to SAP-internal structures. The ERP system performs the same checks on the data as for the corresponding dialog functions.
You have two options for transferring data to the ERP system:
· External Data Transfer with Function Modules
· External Data Transfer with BAPIs
External data is subdivided as follows:
· Master data
· Planning data
· Actual data
