The displayed part name over the table is always the original LINA of the table by default.

This can only be changed via the configuration file psolopt.cfg.

[SETTINGSTABLE]
TABDESCRIPTION=$LINA. additional text

A change of the parts list designation [BOM name] under PARTlinkManager -> Extras menu -> Configure ERP environment -> Parts list designation [BOM name] tab page (plinkcommon.cfg -> block [PARTdataManager] -> key "LINA") only changes the display in the PARTdataManager on the BOM [Bill of material] tab page and not the LINA above the table.
