batch management with transactions

Dear Gurus,

My user has a material which has last transaction in May-2014 and wants to activate the batch management.

I know the total stock and total value have to be removed by any means before activating the BM.

My question is: Whether my work-around will have any bad consequence that you can think of?

My work-around:

As said, last trx is in May-2014. After that all stock/value are cleared.

1. mmpv, change period to July-2014 (with some trick on escaping date check)

2. activate the batch management

3. mmrv - check "allow post to previous period (June-2014)

So that user can continue to post in June (no need to wait a full month)
