To be able to use the function UNIMARC records upload from the Administration tab, the http service of your host need to have read/write access in the admin/import directory of PMB (which is normally the case). In addition your file must not be greater than a certain size (upload limit of your host).

Failing which the solution for importing UNIMARC records will consist in uploading the required file into the admin/import directory of PMB, by FTP for example, then choosing the option "pre-loading" from the import page in Administration. Your file must IMPERATIVELY bear the name unimarc.fic.

To be able to create barcodes, the web server need to have read/write access in the temp directory of PMB.
