Hi SAP Gurus,
I am requesting you to kindly provide some details on the instruction keys maintained and their usages in payments. After going through few of the SCN discussions, i understand that these keys are instructions to the banks about how to carry out the payments. But when i open OB47, i can see that there are 4 fields for instruction keys, a cost allocation key and a payment type. I also got to know that we can maintain instructions against instruction keys in
"Define Instructions for payment Transactions" under Data medium exchange in SPRO.
So my question is
1. What is the functionality of the four keys? It will be great if some one can make me understand how they will be used with a small example
2. If instructions against all the 4 permitted instruction fields are maintained then which one will be used when we are making a payment
3. What is the functionality of the cost allocation key and how is it used in the payment.
It would be really great if someone can answer the above questions with an example.
