Hi Santhosh. In our case we want to rollback our content to its previous version. We have content replicating across two repositories. Once the new version of document is created inside Marklogic a separate request is made to another transactional repository to update certain metadata information for that content. In case of any exception in the metadata repository the latest version of the document in Marklogic which already committed needs to be rolled back to oits previous state.
dls:document-version-delete is used to the purpose for deleting latest version from Marklogic repository in order to rollback content to the previous version. But After deleting the content it is not getting version next time onwards. By the way What is meant by "dls:document-version-delete overrides retention policies"? Thanks for your response...

In your case as you have deleted the document already, so it could not update or create new version in step 7. So, you can try to delete the earlier versions instead of last(), then hopefully your step 7 will wrok fine as you have the latest version. Note: In step 6, you are passing the 3rd argument as fn:false() , this means it will not reatin event he document's property. dls:document-checkout-update-checkin($templateURI,$content,"update",fn:true()) here $templateURI - is the uri of the document to be updated, as you have deleted the document in step 6, it can't find the document with the given URI to update. The documentation for "dls:document-version-delete" says that this function overrides any configured retention policies and should be used with care. So if you want to delete the older versions, before doing step 6 , perform step7 and then delete the older versions. Hope this helps.

Once the latest version of the document is deleted, we are not able to create next version using dls:document-checkout-update-checkin. Here is the sequence of steps performed over xlsx (binary content) Step 1: let $content := BINARY_CONTENT Step 2: let $templateURI := URI Step 3: (:Insert manageable document inside ML:) dls:document-insert-and-manage($templateURI,fn:false(),$content,()) Step 4: (:Creating multiple Version:) for $a in [1 to 13] return xdmp:eval(" import module namespace dls = 'http://marklogic.com/xdmp/dls' at '/MarkLogic/dls.xqy'; dls:document-checkout-update-checkin( URI ,doc(URI),'update',fn:true())", (), <options xmlns="xdmp:eval"> <database>{xdmp:database("db-name")}</database> </options> ) (:Till now we are fine:) Step 5: let $latestVersion := fn:data(dls:document-history($templateURI)//dls:version-id)[last()] Step 6: (:Delete latest version:) dls:document-version-delete($templateURI,$latestVersion,fn:false()) Step 7: (:Ideally next version should be created by this step:) dls:document-checkout-update-checkin($templateURI,$content,"update",fn:true()) (:No versions are getting created:) The retention rule is created to maintained all version of document Let me know in case this is an known issue or we are missing any step.
