Assign a color to your cell in ALV and access another dimension to ALV reporting. With easy ALV it's even easier: 

Setting colors is done by passing an extra attribute with color information to the ALV class. Color information is arranged per field and per line. Effectively any cell can be assigned a color. When whole rows are to be painted, all the fields on the row should be assigned their color. And the same applies to column coloring: simply assign the field (cell) color on every line in the report. Focus on the COLORS field which is available in the data table, hence color assignments become part of the data (colors type lvc_t_scol,).
