Currently this is the help for SUBTOTAL function: https://help.libreoffice.org/index.php?title=Calc/Mathematical_Functions&Language=en-US&System=UNIX&Version=5.4#bm_id3165644 It only shows 1-11 as available function indexes. Codes have been extended with indexes 101-111 to comply with the Excel function of the same name: https://support.office.com/en-us/article/SUBTOTAL-function-7b027003-f060-4ade-9040-e478765b9939 The only difference between the two ranges is that the 101-111 functions disregard hidden rows. The new function indexes were added with this commit: https://cgit.freedesktop.org/libreoffice/core/commit/?id=40575c20ff9cd693b8a6d3627274ce6d745e0581 Setting to NEW based on the referenced sources.
