Summary : 
      SAP Note identifies a runtime termination error DATA_OFFSET_TOO_LARGE (CX_SY_RANGE_OUT_OF_BOUNDS) triggered in module NUMBER_GET_NEXT (LSNR3U01) during transaction execution. The issue results from not adhering to pre-established conditions for enhanced local buffering—specifically, instance names exceeding 17 characters (per SM51). A workaround is using parallel buffering as detailed in Note 599157, but only if changing the buffering type is essential. Further guidance is available in Note 678501.
