For Content Types that use SDL Trados Studio filters, during pre-processing segmentation is performed differently in SDL TMS than in Studio and some mismatches can appear. For example, when using Trados SRX segmentation rules, Studio settings are applied in TMS and segments and paragraphs are preserved "as they are" in Studio. When using Sentence SRX, the TMS Segmentation Rules are applied and every paragraph is considered a segment. On the contrary, Trados SRX segmentation rules treat a soft return in a paragraph as a single segment, while Sentence SRX segmentation rules create a different segment with every soft return within a paragraph.

To work around this situation, you can configure either SDL TMS or Studio to use the appropriate segmentation rule and thus avoid discrepancies.

Option 1: Configure SDL TMS

In SDL TMS, when exporting a package to Studio, select the Studio package format to preserve all the settings and features configured in SDL TMS without further configuration at SRX level as it already contains the SDL XLIFF with the segmentation settings. The return package preserve the settings back to SDL TMS as well.

 

Option 2: Configure SDL Trados Studio

1. In Studio, create a new file type or modify an out-of-the-box filter and export the settings file. To do so, go to File > Options and either create a new filter or modify an existing one. Pay particular attention to the specific file type you are creating/modifying, as this is what you will have to configure later in SDL TMS. 
2. When finished creating/modifying the file type, click the Export Settings button and select a location to store your *.sdlftsettings file. 
3. In TMS, go to Setup > Resources and click New to create a new resource. Fill in the boxes, as required, then click Browse next to the Filename box and, in the Choose File to Upload dialog box, select the *.sdlftsettings file you exported from Studio. 
4. In the Group list, select Pre-processing, and in the Type list, select Options XML File. When finished, click Submit to save your newly added resource. 
5. Go to Setup > Content Types, click Add and then fill in the boxes. Make sure to fill in the MIME Type box with the same File Type configured in Studio (for example, text/xml for a Custom XML Content Type). 
6. In the Pre-processing tool list, select the pre-processing tool that corresponds to the Studio File Type you have downloaded the *.sdlfsettings from. Then, in the Segmentation Rules (SRX) file list, select Trados SRX to preserve the default Studio settings. 
7. When finished, click Submit to save your newly added content type. You can then proceed to add your newly created content type to a Configuration, and use the Configuration to create Jobs that will use the Trados SRX Segmentation Rules. 

This is not a defect in the application, but occurs due to the different default segmentation rules used in Studio and SDL TMS:

The SDL TMS default segmentation rule is Sentence SRX (which is the segmentation rule used by all legacy/SDLX filters) in order to support as much continuity as possible until users switch from legacy to Studio filters.
Studio’s default segmentation rule is Trados SRX.
