Crystal Report layout Design

Hi All,

In AR Invoice, I have 3 groups of numbering series location wise.

Example: for Mumbai location : MB1415

                for Pune Location : PN1415

                for Bangalore Location : BL1415

I have three formats of crystal reports for 3 locations. Now I need to set default Crystal report for location wise. Can anyone tell me how to set?

Help in this issue.

Thanks & Regards.

Saikrishna.
