Flow mapping issues when using target system file

[pweilerERG]

When using the flow mapping feature to map a source flow to a flow in a target system file, we have been encountering two issues:

1. Slow response times when attempting to select a target system flow. We have tried this with small and large databases as the target system and are still encountering slow loading times.
2. Target system flows do not come in with flow categories (flow categories are present in the target file). See screenshot below.
