I have two questions in Materail Ledger closing:
Can we able to close materail ledger from last 4 periods, eventhough materail period is closed and now 7 and 8 periods are opened and also
can we able to run ML closing(including SL/ML/Consumption/WIP and posting for one single material.
There is a bunch of program available using transaction CKMHELP. you can choose the helpdesk for master data to change the period status of the material.
For your second question, if you run ML for 1 single material there will be multi-level determination, so I don't really understand why you want to do that unless you are dealing with trading good. What you can do is to change the price determination of materials you want to exclude to 2 in accounting 1 view of the material master. Or you can use the transaction mentioned by Sean.
