  Hi Experts,

         I had developed SAP SCRIPT, in that there are no. of line items based on line items the color should get change i.e suppose first line items rows should print grey while second  items  rows should not, third line items rows again should print grey and fourth should not...as on...

    How we can color the rows in sap script.

Thanks In Advance,
