hi,

what is the basic difference between transaction code MMPV , MMRV, & MMPI.

i am using MMPV for new period opening and closing at begning of each month.

Now, I have a problem, our company want to close december'2010 (period -09) for quartrly closing of books. how can i do that. there may be scenario that in later date i need to open period -09 for some stock adjustment. I spoke to one of MM consultant and he advice me not to use transaction MMRV in normal scenario, because it may cause inconsistencies in system and it will show difference in diff. reports. is it true?

CAN ANY ONE LET ME KNOW THE WHAT STANDARD SAP SUGGEST IN THIS REGARD. WHETHER IT IS RECOMENDED TO CLOSE PERIOD 09?

THANKS,

Hi,

Initialize Period - MMPI RMMMINIT

Close Period MMPV RMMMPERI

MMPV is an activity where you have to close the prevoius period and you tell the system to allow posting in the current period.In MM we can work with two periods that presnt period ( month) and previous month .For example we have to open the JAN then for the given company we can close the DEC.In this way we can post our postiong in JAN month.

If allow back posting tick is allowed then you can work with JAN and DEC.

Period here is the fiscal year so if you are not comfortable with the Fisacl period then do use the current date for closing period .for example

you want to clos DEC then put today date ( 01.12.2010) instead of giving the periods as different country has different fiscal periods.

Initialize Period - MMPI RMMMINIT

This is to insitailse the period for the company codes.this is not a regular activity.When you system is activted then you have m aintain Company Codes for Materials Management

To create a material master record, the control record must exist for the company code for which you want to create your master record.

To initialize company codes during productive operation, you have to use the period closing program.

There is also one more trancation MMRV to allow the posting to previous period for a company code
