The tool only works if you use it directly from the geoprocessing tool via the ArcGIS Pro graphical interface. However, when run in an isolated Python script, or via ArcGIS's own Notebook, it returns an error and does not change the version to the definition, despite being the same command copied from Geoprocessing.</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="MatheusSparapani_3-1749832899750.png" style="width: 400px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/134345iFE0237CFF6510B4C/image-size/medium?v=v2&amp;px=400" role="button" title="MatheusSparapani_3-1749832899750.png" alt="MatheusSparapani_3-1749832899750.png" /></span></P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="MatheusSparapani_2-1749832724438.png" style="width: 400px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/134344iD02C4ED3720FCD44/image-size/medium?v=v2&amp;px=400" role="button" title="MatheusSparapani_2-1749832724438.png" alt="MatheusSparapani_2-1749832724438.png" /></span></P><P>Another point is that there is no way to check the branch version via arcpy, only via the graphical interface. Not even arcpy.Describe() makes the branch version explicit.<BR /><BR /><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="MatheusSparapani_0-1749832630220.jpeg" style="width: 400px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/134342i61F28A954CCB1D37/image-size/medium?v=v2&amp;px=400" role="button" title="MatheusSparapani_0-1749832630220.jpeg" alt="MatheusSparapani_0-1749832630220.jpeg" /></span></P><P>&nbsp;</P> Fri, 13 Jun 2025 16:42:30 GMT https://community.esri.com/t5/geodatabase-questions/changeversion-in-a-branch-not-working-in-toolbox/m-p/1623502#M9641 MatheusSparapani 2025-06-13T16:42:30Z https://community.esri.com/t5/geodatabase-questions/changeversion-in-a-branch-not-working-in-toolbox/m-p/1623724#M9642 <P>Branch versioning isn't just another flavor of database versioning.
