Hi @Vijayakumar_Raju_CBE The five most recent libraries only allows by
adobe launch that have been published to your production environment for
later retrieval / re-publish. So once the library published into
production or republish any library (from recent most five), you can't
get that library back to dev or staging environment. in your case
Library A. if you think the particular rule / data element has some
issues with your de-active library then fix those issues and save into
new dev library...
