 (b) at least one substitution in the following positions versus SEQ ID NO:5: M202L, M202V, M2025, M202T, M202I, M202Q, M202W, S255N and/or R172Q. 
 
     
     
         3 . An automatic dishwashing detergent composition according to  claim 2  wherein said alpha-amylase has:
 (a) one or more of the following substitutions and/or deletions in the following positions: 
 R118K, D183*, G184*, N195F, R320K and/or R458K; or 
 (b) one of the following substitutions M202L or M202T mutations. 
 
     
     
         4 . An automatic dishwashing detergent composition according to  claim 1  wherein said bleach comprises peroxy acids and/or alkali metal percarbonates. 
     
     
         5 . An automatic dishwashing detergent composition according to  claim 1  comprising a sulfonated polymer. 
     
     
         6 . An automatic dishwashing detergent composition according to  claim 1  comprising at least 1 mg of active protease per gram of the composition. 
     
     
         7 . An automatic dishwashing detergent composition according to  claim 6  and wherein the protease is a low temperature protease. 
     
     
         8 . An automatic dishwashing detergent composition according to  claim 1  comprising a lipase. 
     
     
         9 . An automatic dishwashing detergent composition according to  claim 1  comprising an anti-redeposition agent. 
     
     
         10 . An automatic dishwashing detergent composition according to  claim 1  wherein the anti-redeposition agent is a non-ionic surfactant or a non-ionic surfactant system having a phase inversion temperature between 40 and 70° C. 
     
     
         11 . An automatic dishwashing detergent composition according to  claim 1  wherein the unit dose form is a water-soluble pouch 
     
     
         12 . An automatic dishwashing detergent composition according to  claim 11  wherein said water-soluble pouch is a multi-compartment pouch having a plurality of films forming a plurality of compartments. 
     
     
         13 . An automatic dishwashing detergent composition according to  claim 12 , wherein the pouch comprises two side-by-side compartments superposed onto another compartment wherein at least two different compartments contain two different compositions. 
     
     
         14 . An automatic dishwashing detergent composition according to  claim 11  wherein at least two different compartments contain an anti-redeposition agent. 
     
     
         15 . An automatic dishwashing detergent composition according to  claim 11 , wherein one compartment contains a composition in solid form and another compartment contains a composition in liquid form. 
     
     
         16 . A method of dishwashing in an automatic dishwashing machine comprising the step of placing a composition according to any of  claims 1 - 15  into the product dispenser and releasing it during the main-wash cycle. 
     
     
         17 . A method of dishwashing in an automatic dishwashing machine using a detergent composition according to any of  claims 11 - 15  comprising the steps of: a) placing the pouch into the product dispenser and releasing it during the main-wash cycle; and b) releasing anti-redeposition agent into the wash liquor at two different points in time of the main-wash cycle. 
     
     
         18 . A method of preventing grit formation in automatic dishwashing comprising practicing the method of  claim 16 .
