SALE/BD64

hi all,

i am doing ALE configuration for two systems SAPD47 & ECC5,

in SALE transaction,for both the systems i have created, assigned logical systems, created RFC destination, connection, tested

in BD64 transaction,i have created a model view GETSET,when adding the message to it,

MODEL VIEW : GETSET

SENDER: SAPD47

RECEIVER: ECC5

MESSAGE: MATMAS

and,it is giving an error message saying that,

Logical system ECC5 unknown (Help/long text ->Entry maintenance possible)
