Standing Instructions 
Definition
A collection of data relating to the business partner that is used on a recurring basis. This data is transferred automatically to the financial transactions.
Use
Standing instructions are used as general agreements and are set up with a business partner for processing similar types of transactions.
They are used as default values when creating financial transactions.
Standing instructions form part of business partner data. You can get to standing instructions from business partner maintenance via Company Code.
You can also find standing instruction from the SAP Easy Access screen by choosing Business Partner ® Special Functions ® Standing Instructions.
Standing instructions are not used in Bank Customer Accounts (BCA) or SAP InhouseCash (FIN-FSCM-ICH). In Loans Management (FS-CML) it is only available for payment details.

· Payment details for the business partner for incoming and outgoing payments

· In the standing instructions for correspondence with a business partner you can determine, depending on the business partner, whether an external correspondence type is generally to be printed or faxed.
