Precautions When Translation Files are Awaiting Import
Translation units must have unique IDs. Arbortext Styler manages the IDs to ensure translations are allocated to the correct source. However, if you have exported generated text files for translation, but not yet imported the translations, you should avoid operations that could cause translation units to be duplicated. Duplicates will automatically be assigned new IDs which means they will not be updated by the import of files already exported.
Operations to avoid during this state are:
Copy to module
Paste objects
Paste generated text
Paste Properties
Refer to Adding Modules and Duplicate IDs for information on avoiding duplicate IDs when working with stylesheet modules.
