Depreciation Calculation error

Hi All,

I tried creating an asset today (26th Dec) with a dep.key containing period control 03 (pro-rata from mid-period).

However, the system gives me an error message saying:

10 Federal Tax MACRS

E613 SYST: You cannot determine the period for rule 03 to 12-26-07

What does this mean? I noticed if I give the date as 23rdDec or earlier (23rd dec is mid of 24th period for this yr) it allows me to post.

Please help me understand this error.

Thanks & Regards,

Tejas
