Fiscal Date Pattern changes

Hello all,

we are in the process of changing the fiscal date pattern starting the last quarter of the year, i.e. we are headed to go for a 4-4-5 period.

In this context I understand that there isn't going to any major implication on the Financial reports or on the ageing reports. Can someone please help help me understand if executing the R099103 alone will suffice for the dates in the reports to be taken effect? or do we need to rebuild any as-of files?

can someone please highlight in case any other changes that needs to be addressed as part of the fiscal date pattern change.
