STO route to Sale-purchase route

Hi experts,

Currently we are doing STO steps for transfer of material from one plant to antother plant. Now, our finance deptt wants to stop STO route for stock transfer. Instead, they want to configure it through Sale-Purchase route.

Kindly help in following:

1. What would be the configuration steps

2. What would be the transaction steps

3. What would be the advantages/Dis-advantages by adopting this route.

thanks in advance,

regards,
