Symptom When executing period closing with initialization, you receive a message stating that the program cannot be launched. Before you start period closing with initialization, you must be clear about the consequences of using this function. This SAP Note describes the potential data inconsistencies that can arise if the initialization is carried out in a productive system. The resulting inconsistencies are not the result of a system error. Instead, they are the result of carrying out period closing with initialization. These inconsistencies can, therefore, be corrected only by chargeable remote consulting because period closing must, as a rule, no longer be started with initialization in releases higher than Release 4.5.

Reason and Prerequisites In releases lower than Release 4.6C, SAP Note 369637 is a prerequisite.
Solution In order to run period closing, you must define the parameter ID MMPI_READ_NOTE in the user parameters using the current date in the form YYYYYMMDD (Y=Year, M = Month, D = Day). If you need this additional security function beforehand, implement the attached correction instructions and create the SET/GET parameter MMPI_READ_NOTE. The SET/GET parameter belongs to development class MG and should have the following short text: 'Initializing periods: See SAP Note 487381'. You should also change message MM(016): 'Follow the instructions in SAP Note 487381 before initializing' The SAP System uses the period concept for stocks. Postings are updated precisely for each period in the system. The book inventory balances for the current and previous periods are relevant for posting. As of Release 4.5, the history concept for book inventory balances was implemented. Note that initializing a posting period has the following effects on the period stocks: l
Initializing a posting period for a previous/any other posting period can lead to loss of information for book inventory balances for previous periods! In this case, the book value of the current posting period is used as the basis for the prior period value!
If you want to continue working with this new posting period, you should also run the attached report Z_DEL_HIST_ENTRIES to delete the history entries that are larger than or equal to the new posting period. l
If you need to set the posting period back one period temporarily (and for a small number of postings) in order to correct an error, (e.g. postings still have to be posted to a particular period), you should initialize the posting period back to the old value to ensure that the prior period values do not get lost (posting should be prohibited prohibited while corrections are being made!).
The prior period values / history records (as of Release 4. 5) for the materials posted in this case are, however, imprecise! Report Z_DEL_HIST_ENTRIES should NOT be performed in this case l
If, however, the posting period is set back to a previous posting period and postings are made during this time, all information about the book inventory for the previous periods will be lost!
As of Release 4.5a, you should implement the correction report Z_DEL_HIST_ENTRIES in order to delete history records newer than the current posting period. If this is not done, inconsistencies can arise when the history records are updated.
l
Important! If there are open physical inventory documents that have status "Paid" or for which the "Freeze book inventory" indicator is set, you should discard them in case they relate to a prior period or were created during what used to be the prior period. The inventory difference to be posted is calculated using the current book value for the previous period and the book quantity set in the inventory document (ISEG-BUCHM) and is not the same as the currently valid book inventory for the previous period!
