In our business, it is a rule to keep the billing period open for two days even after the last day of the fiscal period. For example,
P10 ends on 29/10/2011, but that period is not closed until 31/10/2011(P11 date) so that the users can create all the invoices for that month. Please note that period 11 is not opened till 1/11/2011 (after closing p10).
Now,order related invoices are created thru an interface program. The user only sends in the "service date" which is mapped to the fixed value date field in SAP and we have defaulted the system date as the billing date to enable posting. The problem arises for the invoices created on the two days mentioned above as the invoices will not post into accounting if the billing date is 30/10 and 31/10 as P11 is not open yet.
How do i make sure that invoices created on the two month end days post into accounting with a billing date of 29/10 (a P10 date)? I can use the FM- FI_PERIOD_CHECK to check if the billing date is in the open period, but how do i populate the billing date field as an open period date automatically without manually changing it for all the invoices that have not posted?
The service date sent in has to be mapped to the fixed value date field because of aging purposes.
Would appreciate your valuable help here.
