Solved: Client issue with ALE Configurations

Former Member · ‎08-22-2011

Hi Experts,

I am trying to connect to a different SAP System through ALE. I have defined logical systems. When i am trying to assign destination logical system to destination client, i am getting an error - "Entry already exists" as there is another system aready assigned with this same client number.

My Question is - Is there any way to connect to 2 Diff SAP systems having same client number? Otherwise, if there is a client (Say 400) that is already assigned to an SAP System, Then cannt we connect to another SAP system having the same client number( 400)?

Rgds,

SURYA.

Hi Surya,

Sure you can! I'm feared to understand that you went to SCC4 transaction in the source system, to add a new entry with client of target system? You shouldn't! The logical system has to be entered in WE20 transaction, to which you assign an RFC port, that you have to maintain in WE21 and SM59 transactions, where you indicate target system and client.

Does it mean, We will use SCC4 only for communcations of the clients of a same SAP system?

In such case, for communcation beween 2 different SAP Systems through ALE, how will we distribute model as i believe, here we need to mention the clients to which the model is to be distributed?

No, SCC4 is only for defining the clients of current system (and the corresponding logical system, which must be unique throughout the landscape), it's not about communication at all (apart the logical system).

Use SM59 to define an RFC destination, you'll define the target host and client .

Use WE21 to create an RFC port, referring to the RFC destination above.

Use WE20 to assign this RFC port to the logical system.

By "distribute model", I don't know if you're talking about the "distribution model", in that case I recommend you to go though this thread where there are general information :
