How to change cm:creator ,cm:modifier for a document ?

[vinayasree]

I have written a custom function uploadFileinAcs() which uploads files to Alfresco. Every time when a document is uploaded through this function I want to change the name of cm:creator and cm:modifier to some "xyz". How do I achieve this?

It's not recommended to modify those fields, since they are protected by the "cm:auditable" aspect.

You may change this behaviour, but it would provoke some side effects on the system.

It should be better to add some custom aspect to include these properties.
