Note As of SAP Release 4.5B, a logical system can be assigned to an RFC destination according to business object type methods (choose the "Special method destination" pushbutton). This requires that the addressed business object type is available in both systems, which is not the case in SAP Records Management. In addition, the BOR runtime environment does not support the enhanced ALE Customizing. This means that, as of Release 4.5B, you cannot use the enhancements in the ALE environment for the BOR service provider.
