Phantom item -correction

Hi All,

We have huge BOM and there are several sub-assemblies in it, I decided to make some sub- assemblies as Phantom, as it was very small BOM, no specific reason to build and store it , So logically it will be built at the time of Parent assembly only,

job has been released and completed. Now, out of some only 1 needs to be corrected as Serial controlled assembly which means non-stock and Phantom option needs to be removed and unable Serial controlled option which will allow me to crate job for it.

is it possible to do so, after one transaction has complete?

Thanks,
V
