Hi António,
The issue you describe being unable to use GAIT 23 is due to a missing entry in your GAIT_SESSION_CONFIG.xml file located in the C:\ProgramData\Esri\Production10.3\Desktop\DefenseMapping\ directory. To resolve this issue:
1. Close ArcMap/ArcCatalog
2. Open the GAIT_SESSION_CONFIG.xml file in a text editor like Notepad
3. Add the following entry:
<GAITParameterValues version="23">
<Schemas>GIFD|GIFDNUNANPO|FACC|FACCNUNANPO|VMAP|VMAPNUNANPO|MGCP3|MGCP4|UFD1|UFD1NUNANPO|UFD2|UFD2NUNANPO|UFD3|UFD3NUNANPO|TDS4|TDS6|NFDD|NFDDNUNANPO|DFDD|DFDDNUNANPO|SAC|GGDM|GGDMU|GGDML|GGDMR|GGDMG|TREX</Schemas>
<Specifications>USE_DFEGMASTER|USE_MGCPMASTER|USE_UFD1MASTER|USE_UFD3MASTER|USE_TDSMASTER|USE_SACMASTER|USE_TREXMASTER|USE_NOMASTER</Specifications>
</GAITParameterValues>
4. Save and close your text editor
5. Restart ArcMap/ArcCatalog
Regarding your issue being unable to write the GAIT errors to a reviewer table, can you please tell me which tool you are using? The GAIT geoprocessing tool in the Defense Mapping toolbox, or the GAIT Session tool on the Defense Mapping toolbar?
