[ABAP] Webservices in a Cluster Environment

Hi Experts,

I developed several webservices to create communications between 2 different environments (SAP and Microsoft).

At this time, every communication works well because the IP Server has been specified automatically in hard via SAO_MANAGER during the creation of each Webservice.

But when the cluster will choose another server for any reason, I probably will be facing a dump (no server found).

My question is:

Do you know, how can I create a correct Webservice with the Server address of the Cluster and not with the Server Instance address ?

Thank you very much.

Rachid.
