Hi, I posted a while ago about Sync Frameworks suitability for merging data between heterogenous schema. My situation is that I have 18 databases, that we can call clients, and one master database i want to sync changes to.
The master and client schemas are identical except the all tables in the master have an extra column - ClientId, to indicate which client the data came from.
I have written my own custom provider that works ok if all the Id fields are unique (as expected). In the public void SaveItemChange(SaveChangeAction saveChangeAction, ItemChange change, SaveChangeContext context){} method, i am adding ClientId to the incoming
item before saving it to the master. This works fine, but if a an item coming from ClientA has Id 1, and Id1 is not in the master, the item is stored successfully with a Client Id of A. However, if an item then comes from ClientB also has Id1 also, sync framework
tries to overwrite the old Id1. Instead I would like to add this as a new row, with the same Id and a Client Id of B. I cannot modify the client schemas in anyway, but I can add new databases if required.
Is this even possible or am I trying to use Sync Framework for what it wasnt intended?
