Excisable Column Disabled

Hi Experts,

Previously i was using SAP B1 2005B PL40. But now i have upgraded to SAP B1 2007B PL10.

Now in 2007 B PL10 i am facing a problem. In the SO, Delivery & A/R Invoice template the Excisable Column is Inactive.

Even in the form setting i have checked , it is showing the Visible column as enable but the Active column is disable.

Is there any idea of SAP behind this change. If not then guide me how to make the Excisable Columns as Active in the SO, Delivery & A/R Invoice template.

Thanks and Regards,

S Manikandan
