Thanks @netchampfaris
I tried using Custom DocPerm. Issue is when exported it doesn’t export fields parent / parentfield and parenttype for tabCustom DocPerm.
As a result when values are imported fields parent / parentfield and parenttype remains blank.
And when the role is accessed using “Role permission manager” it gives error Doctype None
Below is snapshot of source table, Columns have values
Below is snapshot of target table. Columns are blank
Am i missing something ? here or it is a bug. Kindly advice. thanks
