Hi Krishendu Das,
1. Post the same amount to current period stock (for example, using
movement type 561) so that previous period stock and current period
stock are identical.
2. Make a withdrawal posting in the previous period for the stock
together with posting date (for example, using movement type 562).
You can now try again to change the base unit of measure or the batch
management requirement indicator.
Since the posting of the previous period values to zero is identical with
posting to the stocks of the current period, you should reverse the above
stock postings (i.e. the stock from the previous period should be booked in
again) to make sure that the stock values from the previous and the current
periods correspond to the state before the change. Please note, however,
that the postings are then carried out using the changed master data from
the current period (e.g. account determination, etc.)
Regards,
Thimmaiah
