All tables keep so called line IDs in the background. They were continuously (and invisible for the creator) added, when e.g. new table lines were created with PARTdesigner (PARTeditor). These line IDs are later also an important reference in the ERP system. Therefore it should always be considered to change the tables as little as possible, because by deleting and adding table lines also new line IDs will be created. It should especially be avoided to delete and newly create a tab file during a catalog update. This sometimes seems comfortable for the catalog creator but this can cause very fatal problems in the ERP system, because all existing line ID references will go lost there.
