Output header and overrides

Origin override

Destination override

Flight number override

Registration override

Scheduled movement date override

Select the date from the calendar. The browser displays it in the local format, for example 22.07.2026, while the LDM header uses only the day.

SI override

When entered, this replaces the SI/suppInfo section from the previous LDM.

Operation mode

Generate from Previous LDM only
When selected, CPM and FFM are ignored. Positions, weights, flagging and volume are taken exclusively from the Previous LDM; only the overrides above are applied.

CPM

Authoritative source for position, ULD destination and gross weight. Merged empty positions such as -52_53/N are split into separate rows.

FFM (optional validation)

FFM weights are not used to build the LDM. They are compared with previous-LDM net weights and reported as warnings.

Previous LDM

Mandatory source for tare, net, flagging and SI/suppInfo. Tare and net are never calculated from CPM or FFM.
