Instead, differences involving the following record types display a read-only comparison and allow a choice between updating and reverting: - sys\_choice \[Choice\] - sys\_choice\_set \[Choice Set\] - sys\_ui\_form \[Form\] - sys\_ui\_list \[List\] - sys\_ui\_related\_list \[Related List\] - sys\_ui\_section \[Form Section\] - wf\_workflow \[Workflow\] - wf\_workflow\_version \[Workflow Version\] Team Development, Resolve Collision page: **Use Pulled Version** and **Use Local Version** options. Upgrade History, Compare to Current page: Comparing non-current update versions to current update version. Allows only **Revert to Base System** option. ## Field types that do not support merging The following field types do not support individual merging between versions or updates: - auto\_increment \[Auto Increment\] - auto\_number \[Auto Number\] - breakdown\_element \[Breakdown Element\] - catalog\_preview \[Catalog Preview\] - collection \[Collection\] - color\_display \[Color Display\] - composite\_field \[Composite Field\] - compressed \[Compressed\] - counter \[Counter\] - currency \[Counter\] - data\_array \[Data Array\] - data\_object \[Data Object\] - data\_structure \[Data Structure\] - date \[Other Date\] - datetime \[Basic Date/Time\] - days\_of\_week \[Days of Week\] - document\_id \[Document ID\] - due\_date \[Due Date\] - Email \[Email\] - external\_names \[External Names\] - field\_list \[Field List\] - float \[Floating Point Number\] - glide\_action\_list \[UI Action List\] - glide\_precise\_time \[Precise Time\] - glide\_var \[Glide Var\] - image \[Basic Image\] - index\_name \[Index Name\] - int \[Integer String\] - integer\_time \[Integer Time\] - ip\_address \[IP Address\] - journal \[Journal\] - journal\_input \[Journal Input\] - journal\_list \[Journal List\] - long \[Long Integer String\] - mask\_code \[Mask Code\] - metric\_absolute \[Metric Absolute\] - metric\_counter \[Metric Counter\] - metric\_derive \[Metric Derive\] - metric\_gauge \[Metric Gauge\] - mid\_config \[MID Server Configuration\] - month\_of\_year \[Month of Year\] - multi\_small \[Multiple Line Small Text Area\] - name\_values \[Name/Values\] - nl\_task\_int1 \[NL Task Integer 1\] - order\_index \[Order Index\] - password \[Password \(1 Way Encrypted\)\] - percent\_complete \[Percent Complete\] - ph\_number \[Phone Number\] - phone\_number \[Phone Number \(Unused\)\] - phone\_number\_e164 \[Phone Number \(E164\)\] - price \[Price\] - reference\_name \[Reference Name\] - related\_tags \[Related Tags\] - reminder\_field\_name \[Reminder Field Name\] - repeat\_count \[Repeat Count\] - repeat\_type \[Repeat Type\] - replication\_payload \[Replication Payload\] - schedule\_date\_time \[Schedule Date/Time\] - short\_field\_name \[Short Field Name\] - short\_table\_name \[Short Table Name\] - Slushbucket \[slushbucket\] - source\_id \[Source ID\] - source\_name \[Source Name\] - source\_table \[Source Table\] - string\_boolean \[<none>\] - sys\_class\_name \[System Class Name\] - sysrule\_field\_name \[System Rule Field Name\] - table \[\] - text \[\] - time \[\] - timer \[Timer\] - translated \[Translated\] - tree\_code \[Tree Code\] - tree\_path \[Tree Path\] - user\_image \[Image\] - user\_input \[User Input\] - variables \[Variables\] - version \[Version\] - video \[Video\] - week\_of\_month \[Week of Month\] - wide\_text \[Wide Text\] - wms\_job \[WMS Job\] - workflow \[Workflow\] **Related topics** [Resolve a collision in Team Development](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/application-development/team-development/t_ResolveACollision.md)
