I would extract the data for both libraries into different datasets, sort by memname and use a data-step to merge both. Depending on the result generate statements for proc datasets.

Is there any ease way to verify which tables were created or modify from one library and copy only these tables to the second one? And if any table was delete (not appear any more on firts library) delete it from the second library too?</P> <P>&nbsp;</P> <P>Regards,&nbsp;</P> Mon, 08 Jun 2020 15:45:06 GMT https://communities.sas.com/t5/SAS-Programming/Copy-between-library/m-p/654573#M196555 MariaD 2020-06-08T15:45:06Z https://communities.sas.com/t5/SAS-Programming/Copy-between-library/m-p/654616#M196560 Just an idea:<BR />Have a look at sas help.vtable, imho you will find all necessary information in it.
