Summary :
In an SAP Early Watch Alert, data for a remote database may be absent even with correct configuration and SMSY settings. The issue arises in the CL_DSWP_SSA_SESSION_HANDLER->DETERMINE_SYSTEM_TYPES method, which incorrectly eliminates duplicate database entries from the internal table, lt_databases, based on overly strict criteria including product and dbname fields. This results in erroneous identification of systems without remote databases, especially when multiple databases are maintained in SMSY, with some not marked as ACTIVE. The correction involves adjusting the DELETE ADJACENT DUPLICATES statement to also compare the instance field.
