Selection lists in M-Files are able to be assigned values from Intrexx data fields or static values. Please note here that the value in Intrexx can be used to determine the corresponding entry in the selection list in M-Files. If an Intrexx field of type Integer is selected for the assignment, you must ensure that the M-Files selection list contains a corresponding entry with the same ID value. Alternatively, the entry can be detected in the list through the displayed value. If a string field is assigned to the list field, for example, the value stored in it must correspond to the displayed value in the M-Files selection list. Please make sure that the letter case is correct here.
The strategy you choose here depends on the application case you want to achieve. If the IDs of the list entries are known in M-Files, the entry should be determined based on the ID. If this is not the case, determining the entry based on the displayed value can be used.
The corresponding dialog for this is opened via Options behind an M-Files Lookup/MultiSelectLookup field. By default, the values are determined via the ID.
