The setWindowSize() method informs the TGenClient library of the maximum size of a match window and what to do if the size is exceeded. This value overrides the maximum window size set in the Relationship Linker’s settings file. The default maximum window size is 50,000 records.
setWindowSize() is not used with SAP clients. Window size can be controlled through the SAP server.
