Hi, I don't know how can set values on Entity, for example, I create a entity for Office and I want to insert a list of offices (migrate for another application) , but I don't find the option for do that, can you help with this. Thanks.
If there is a REST or webservice interface, you could use the mendix methods to connect to them.
Check out the academy, there are some examples how to implement it.
You could use the excel import module from the app store.
