Hello Marcel,

Based on your description, it seems like you're encountering an issue with merging segments in Trados Studio. This could be due to the structure of the document you're working on. Trados Studio is designed to respect the structure of the original document to avoid any potential damage.

Here are a few things you could try:

Step 1: Check if the segments you're trying to merge are within the same paragraph. Trados Studio only allows merging of neighboring segments within the same paragraph. If there's a paragraph mark or a hard return between the segments, or if they're in different cells of a table, they cannot be merged.

Step 2: Look at the document structure column (the last column) in the Editor window. If you see a capital letter 'P' to the right of the segments you're trying to merge, it means they belong to different paragraphs and cannot be merged.

Step 3: If you're working with an XML document, ensure the segments you're trying to merge reside within the same element. Segments within different elements cannot be merged.

Step 4: If none of the above apply, you might want to check your segmentation rules. Sometimes, the rules might not segment the text in a way that makes sense for your translation. In such cases, you might need to adjust your segmentation rules.

Remember, changing the segmentation by merging or splitting segments can affect the matches from your translation memory, as the segmentation in the memory might become different from the segmentation in the document.

I hope this helps! If you have any other questions, feel free to ask.

Best regards,

Is your file a xml or xliff document? In this case merging may indeed be problematic. If you still want to merge the segments, use an older version of Studio or wait for the next update/upgrade. To my knowledge this message will be a warning then instead of just preventing merging.

My file is an xliff document. What's strange is that merging works with some segments, but not with others.

It will not work for example for segments, where formatting tags are included and closed in both segments, which previously belonged together. Trados Studio closes formatting tags for each segment, so when you merge a superfluous tag pair may appear in the segment and break the import of the file at customers side. Please note, that this is only one possible explanation.
