Hi,

OMSY to fix up the Initial Period and Year for a company code for material management .After setting you should touch this setting & used only once. For opening & closing periods in MM side, you used MMPV and MMRV to set back posting allowed and to check which period is open in SAP system.

OB52 is used for FI side only. It control period in all Account Types A, K, D,M, S and specially Account Type ?+? which stands for valid for all accounts type .

We use OMSY to fix up the Initial Period & year of a compnay code when we start the implementation. Later this transaction will not be used for this company code.

Later for opening & closing periods in MM , MMPV transaction will be used.

OB52 is used for setting the Open periods & open special periods for the account types & accounts.

This transaction will be used every month for opening & closing periods in FI.

Hi,

OB52 - Is done on the finance side.... for a fisical variant they define the periods from and to for different account types. they can also define special posting periods also.

OMSY - Is done and maintained by MM people.. here we maintain the company code for materials management. we can see which is the current period of posting, we can see the previous month of posting. a setting can be done to allow back postings also.

OMSY -- MM periods are maintained and you can not Roll back to the closed periods

OB52 -- FI Periods are maintained and you can open the closed periods as per the client requirement..

and the MM periods should be in synchronization with the FI peridos, then only you can Post the MM documents..

apart from OB52 FI periods are maintained date specific in OB29 trxn...
