IDOCs are the intermediate documents which act as the container for the data. IDOCS are used in sending the information between SAP systems.

IDOCs are of two types

1. Inbound IDOCs
2. Outbound IDOCs

Inbound IDOCs

     Incoming IDOCs to the SAP system are called as Inbound IDOCs.

Outbound IDOCs

     IDOCs which are sending out of an SAP system are called as Outbound IDOCs.

Each IDOC will be associated with

1. Unique IDOC number
2. Control Record (EDIDC table)
3. Data Record (EDID2 / EDID4 tables)
4. Status Record (EDIDs table)
