The French Structural Business Statistics (SBS) production system, known as ESANE, has two main uses: - production of statistics based on the European SBS regulation; - estimation of businesses’ contributions to GDP for the national accounts. ESANE is currently changing to produce estimates based on profiled units or enterprises and no longer on legal units. Several methodological studies have been conducted to support this change, and the following study concerns the adaptation of the treatment of influential values by winsorization for the dissemination of results at the enterprise level. To manage the update of the set of legal units belonging to each enterprise, the generalized weight share method is used. The aim of this study is so to adapt the Kokic and Bell's method of winsorization to a weight sharing. We compare four scenarios with a simulation study based on the ESANE data 2016.
