Sap activity, which transforms excess ingested sugar into long-chain oligosaccharides." A much larger set of animals do however consume phloem sap by proxy, either "through feeding on the honeydew of phloem-feeding hemipterans. Honeydew is physiologically less extreme than phloem sap, with a higher essential:non-essential amino acid ratio and lower osmotic pressure," or by feeding on the biomass of insects that have grown on more direct ingestion of phloem sap. Maple syrup is made from reduced sugar maple xylem sap. The sap often is harvested from the Sugar Maple, "Acer saccharum". In some countries (e.g., Lithuania, Latvia, Estonia, Finland, Belarus, Russia) harvesting
SAP Business Connector version independently: SAP (who had acquired the full core Integration Server source code) started developing SAP BC 4.7, while webMethods began work on wM IS 6.0. Of course the component that changed most in SAP BC 4.7 was the "SAP Adapter", which got enhanced IDoc processing capabilities and performance improvements in the RFC communication layer. However, SAP also enhanced selected components of the core Integration Server, e.g. the job scheduler, the "Reverse Invoke" feature and the WmPartners package, which was completely redesigned. SAP tried to do these core enhancements in a backward compatible way, the only exception being the WmPartners
