Hi Nathalie,
Please run "Product Alerts Report" under Actions-> Schedule Task. Refer to Column E/EoSale Date.
Respective EoL notices are also listed in Column C.
Hope it helped?
Regards, Vivek
Yes it is available in SNTC portal. If you would run a product delta report or inventory management report, you would see a column "EOS" which gives Last Day of Sale information.
