Summary :
Issues persist with ABAP Web systems communicating with the System Landscape Directory (SLD), particularly in achieving reliable access with success rates significantly below 100%. Problems arise primarily from the use of shared Program IDs in the JCO/RFC framework, leading to the incorrect routing of requests to RFC servers. For settings involving the ABAP API, RFC destinations like SAPSLDAPI and LCRSAPRFC in SM59 or SLD-specific settings in JCO/RFC are prone to mismatches causing erratic behavior. Resolutions include unique configuration of RFC servers and ensuring standalone gateways for individual SLDs to prevent overlaps or conflicts, particularly in systems using transaction RZ70 and SMGW for monitoring and registration.
