For our Utility Network Migrations we have leveraged the Data Loading tools. We started with Version 2.4 and Pro 2.5 I believe.
We have since moved to Pro 2.7 and the Data Loading tools 2.7.x.
After this migration we have noticed that if the source data has subtypes, the DLT's try to break each of these subtypes into a separate spreadsheet based on how the tool THINKS the data should be mapped. How can we prevent this? It looks like if there is a matching subtype in the target the tool will generate a separate spreadsheet for that particular source and target.
When this happens we get numerous spreadsheets (attached) as well as the subtype tab being removed from the spreadsheets. We have used this tab in the past to map our data. Also attached.
Basically is there a way for the data loading tools to not try and do this much. It worked well for us when it didn't try to predict as much...
