Blank Rows in Input Template

Dear BPC Friends,

I am working on designing a input template  for ‘Cost Center’ budget planning. In the template  I have ‘Cost Center’ and ‘Account’ in Rows and ‘Time’ in column.

The Client want to have blank rows  so that they can manually enter the ‘Cost Center’ & ‘Account’  or do a cut past if from other excel sheet.

I am confused how to have blank rows in the row range. Kindly advice.

I am working on BPC 10 NW.

Thanks,

Rahul
