The SAP error message RSO_CTC252 indicates an issue with the delta load process in SAP BW (Business Warehouse). This error typically occurs when the last delta request is considered "old," meaning that the delta data that is being attempted to be loaded is outdated or not in sync with the source system.
Cause: Old Delta Request: The delta request that is being processed is older than the last successful delta load. This can happen if there have been changes in the source system or if the delta queue has not been processed in a timely manner. Data Inconsistency: There may be inconsistencies between the source system and the BW system, leading to the delta not being able to be loaded. Initialization Required: If the delta queue is too old, it may require a new initialization of the data source to reset the delta process.
Solution: Check Delta Queue: Verify the delta queue in the source system
