Create new fiscal periods 5-4-4 OB29

Hi all experts.

I would like to setup new fiscal periods in OB29.

Period 1 should be from january 1st to february 4th.

Period 2 should be from february 5th to march 3rd.

and so on.

I create a new year dependent fiscal period variant, and go to the period folder.

What do i put in month, day and period to reflect the periods mentioned above ?

Will it be correct to set the following?:

Month 2

Day 4

Period 1

(for period 1 from january 1st to february 4th)

Month 3

Day 3

Period 2

(for period 1 from january 1st to february 4th)

?

And how will this affect other areas in SAP - Material planning ?

Thanks for answering! Points will of course be rewarded.
