The purpose of ALE IDOC is to help the ABAP Developers to get an idea on how to setup all the necessary configs needed to send and receive idocs. This is the MUST guide for you if you are wondering where to start with the ALE IDOC Development and this pretty much covers around all the required business cases. All the below steps are explained in detail.

Useful EDI Transactions
- VOE1 Translation between EDI categories and SD item categories
- VOE2 Table EDSC view. Customer link to sales area detail.
- VOE3 Table view EDPVW. Add partner types that will be transferred to the IDoc.
- VOE4 Table view EDPAR. Link external partner number with our internal number.
- OVAI Create entries for each Vendor / Partner description combination. (Vendors must match sold-to Acct. at Cust., and Partner descriptions must match ship-to Partner descriptions.) This transaction updates table T661W. SAP uses this table to determine the schedule agreement, sold-to partner.
