GR Reversal XML failed in SNC

Hi

I am sending GR reversal information through RSMIRPOACT2 report from ECC to SNC but XML in SNC is in failed status with error : Error while processing message payload An error occurred when deserializing in the simple transformation program /1SAI/SASA149DFD904DAE7E738DF The value ' 100.000-' is not in the value range of the XML schema type 'decimal' or it does not meet the specified limitations

I also confirmed that negative stock check box is checked in below path:

SPRO >> SCM Basis >> Logistics Inventory Management Engine (LIME) >> Basic Settings >> Application-Specific Settings >> Determine Global Customizing Settings for Each Client

Please suggest.
