SAP - How to Open closed MM period (MMPI)

MMPI (Initialize Period) is a standard SAP transaction code available within R/3 SAP systems depending on your version and release level.
Please follow the following procedure, so that you can open & Close the previous period smoothly:
1. Lock all users out of PRD system.
2. Add User parameter MMPI_READ_NOTE with value = current date in this format YYYYMMDD
3. Stop all processing that updates inventory values.
4. Run t-code MMPI with the correct period after running MMPI just enter the period which you want to open.
5. Close the period as soon as your work gets completed, because it is very risky to open the previous period for a longer time.
Note: The MMPI can make inconsistency in material ledger record, it will affect the cost of the material so you need to work around to change the material cost manually.
