Remove stock and revert it to warehouse to activate batch managmt-BestPract

Question

Hello,
My client wants to start using batch management.
To do so Iu2019ve 3 options:
1st u2013 Create a new Plant and replicate on it every material. Transfer the existing stocks to the temporary Plant. Activate Batch Management. Transfer from temporary Plant to the original Plant with the respective batches.
2nd u2013 Create a Sales Order for a temporary Customer with the same internal price and create invoice. Activate Batch Management. Create Purchase Order for a temporary Vendor and make the goods receipt and invoice. Both customer and vendor should balance each other. So does stock accounts.
3rd u2013 Make a goods issue to a specific cost center. Activate Batch Management. Make a goods receipt with movement 501. In this case Iu2019m not shore about the financial implications.
Can anyone help based on the experience for each way should I go???
Thanks,
BMO.

SAP provided two reports which can update or remove BATCH MANAGEMENT INDICATOR and BATCHES without removing the material stocks and documents. We need to close only open physical inventory documents.
The below reports update, all relevant documents based on batch activation/de-activation:
u2022 RVBCONVMAT2BM - Sets the batch management requirement indicator.
u2022 RVBREVMATBM - Removes the batch management requirement indicator
But,these programns will not be available in standard SAP,they has to procured form SAP.
