HI,

You can achieve through versioning in KM!

Refer the below document

Hi,

Please follow the document with stepbystep. it should work.

for versioning find the below sample code.

Note: This document based on NWDS 2.0.14 version

if (resource.isVersioned()) {

// if yes check out it if not done already

if (!resource.isCheckedOut()) {

com.sapportals.wcm.repository.ICheckOutInfo outInfo =

resource.checkOut();

}

Hi,

Initially PathRID should be

RID pathRID = RID.getRID("/documents/SDN/");

If you pass same PathRID in the catch block the exception will occur com.sapportals.wcm.repository.NameAlreadyExistsException

To avoid the above exception use below PathRID

In the catch block (in the time of versioning) Path id should be

RID pathRID = RID.getRID("/documents/SDN/"+Version);

Where Version is name of the file.

Hope you are understood the version concept.
