Note 487381 - RMMMINIT: Protection against unintentional execution

Note Language: English Version: 23 Validity: Valid from 04-24-2003



For period closing with initialization, the system displays a message saying that period closing cannot be started.

Before you start period closing with initialization, you must be aware of the consequences of period closing with initialization.This note describes the possible data inconsistencies that might occur if you carry out the initialization in a productive system.The resulting inconsistencies are not to be traced back to a system error but they are a result of the period closing program with initialization.

Hence, these inconsistencies can only be corrected within the remote consulting purchased separately since normally you no longer need to start the period closing program with initialization in a release > Rel. 4. 5.

Cause and Prerequisites

The prerequisite up to Release 4.6C is the implementation of Note 369637.


In order to be able to have the period closing program running, you must reserve parameter ID MMPI_READ_NOTE with the current date in the user parameters with the current date in form YYYYMMDD (Y = year, M = month, D = day).

If you already need this additional security beforehand, implement the attached correction instructions and create SET/GET parameter MMPI_READ_NOTE.The SET/GET parameter belongs to development class MG and should have the following short text:

'Follow the instructions in Note 487381 before initialization '.

In addition, change message MM(016):

'Follow the instructions in Note 487381 before initialization'.

The SAP system works with the period concept of stocks.In the system, postings are updated precisely to the period.The inventory balances of the current and of the previous period are relevant to posting.As of Release

4.5, the history concept of the inventory balances has been introduced as an enhancement.

Bear in mind that the initialization of a posting period has the following effects concerning the period stocks:

o The initialization of the posting period to a previous or to any posting period may lead to the loss of the information of the inventory balances of the previous periods.The book value of the current posting period is taken as the basis also for values of the previous period in this case.If you want to continue working with this new posting period, in addition you should execute report Z_DEL_HIST_ENTRIES attached so
