Hi , i have accidentaly deleted the TVRRUR table mapped with SAKUR and SAKUC line in ova2 T code . Once we go inside OVA2 T code we can select sales item (2) and then click on RR ( revenue recognition) Procedure and then go click on fields , here we can find 5 to 6 list of tables .. here i accidentally deleted 2 lines like TVRRUR table line. in the below screen shot the TVRRUR both the line i have deleted.
