like "Could not determine BW release of logical system"

any idea would be helpful and thanx in advance..

Hi loknath

After changing the mode from F to D, Just mention the Bw logical system name in Target sys field.


System, in which applications run, integrated on a joint databasis.

In the SAP sense, a client corresponds to a logical system. In the

definition of a client, you can enter which logical system is a client.

The logical system is relevant for the following SAP areas:

o ALE, in general: Communication takes place between one or more logical systems.

o ALE, distribution scenarios (e.g. cost center accounting):

Definition of the system in which a certain application is running.

Master data changes, for example, can only be carried out in this system.

Workflow objects: The logical system is always contained in the key of an object

When maintaining the logical system, please note:

o The logical system must be unique across the group. It may not be

used by any other system in the ALE system group.

o The logical system may no longer be changed in the productive system

if a non-initial has been entered once. If a non-initial logical

system is changed retrospectively then the system's own documents

may no longer be found. If the logical system of a document

reference does not agree with it's own then the system assumes that

the document is in another system.

If your problem is solved...why you don't close the thread !?

Hi dear!

You have to add also the logical name of your BW target system in the dedicated field !

You channels have as key datasource name AND bw destination system (you can verify it in RSA7 columns!)

Hope it helps!



...please don't forget to reward the's THE way to say thanks here !

in addition to Robertos info, your datasource already has to be assigned to a infosource in a bw system. Otherwise it is not possible to simulate a init or delta load in rsa3.
