How we can enable Item track location serial number while we have stock?

Hi,

We recently installed Produmex on one of our SAP B1 company (ver 10) and before we move serialized item stock, we forgot to set PMX UDF U_PMX_TLSN to true and causing we can't get the SSCC/LUID info from each serial number. In this situation, how we can enable this UDF without removing the stock? Because removing the stock and put them back is a huge work for us. Any suggestion?

SAP B1 ver: 10.0
Produmex ver:  2024.12.02.0024

Thanks,
