Hi @ashiq_097 

Please share what configuration do you use for the versioning schema.

What do you expect and what you get. for example, I want the previous version from AB and I do not get AA please describe it more widely 

How the code is written? It could help to test it and help you.

LOGGER.debug("Enter -->getPreviousRevision");

RevisionControlled retValue = null;

WTPart prevVersion = null;

String actualRev = object.getVersionIdentifier().getVersionSortId();

try{

QueryResult allVersions = VersionControlHelper.service.allVersionsFrom(object);

RevisionControlled prevRevision = null;

while (allVersions.hasMoreElements()) {

    Object obj = allVersions.nextElement();

    if (obj instanceof RevisionControlled) {

    String checkRevision = ((RevisionControlled) obj).getVersionIdentifier().getVersionSortId();

    if (checkRevision.equals(actualRev)){

    // next version

    }else{

    RevisionControlled subprevRevision = (RevisionControlled) obj;

    State state = subprevRevision.getLifeCycleState();

    if (state.equals(State.toState("RELEASED"))) {

    prevRevision = subprevRevision;

    break;

    }else{

    actualRev = subprevRevision.getVersionIdentifier().getVersionSortId();
