P6 show Fiscal Calendar Weeks

Hi Guys, Looking for a bit of help with a layout.

I work in the rail industry. We work on weeks everyone on the project refers to project weeks and not dates.

The weeks run from the First Saturday In July to the Last Friday the following June. (I.e Week 1 = first Saturday July to Following Friday etc)

• I have set the batch financial periods to every week starting saturday for the next 10 years.
• Ordinal Dates keep - running (ie does not reset back to week 1 after week 52)
• Using Fiscal I can get FY2012, FY2013, FY2014 etc with FM01, FM02>>>>>FM12 etc

I want to show the week numbers on the timescale like FW01, FW02 etc to FW52 and then Starting at FW01 again the following July,  but not having much luck.

Can anyone help?

Cheers

Rob
