Sometimes, the Client requirement comes to reopen the MM closed period which is not possible directly through the MMPV t-code but We have one solution where we can achieve this requirement quickly.
There are some prerequisites before doing this activity because it's susceptible activity. So we have to do such type of activity very carefully.
1. lock all the user IDs related to GRN, MIRO & Material transfer, or Goods issue.
2. In this period no transaction should happen in MM.
3. Even no account activity should happen.
Process:-
Go To SU3 T-code or SU01 and enter the user Id who wants to do the activity.
In the above screenshot, the 09 periods is opened so now we need to come back date period so we will try to open the 04 periods.
So use the T-code: MMPI and enter the company code & period which you want to reopen.
execute it.
So now, the previous period is open.
After completing the activity, you can back to the current period also with the same process.
