Description:
Get the errors as below when trying to open models, saved by other users, from the Mart.
"The mart model could not be upgraded to the current metamodel level"
"A model processor could not be found to convert metamodel"
Solution:
This error occurs if you try to open a model that was created and saved in a later version of erwin Data Modeler, so the user experiencing the error most likely has the wrong version of the erwin DM client installed. For example, if user A saves a model into a 2020 R2 SP1 Mart using the correct 2020 R2 SP1 client and user B tries to open the model using the 2020 R2 (Non SP1) client, then they will get the above error. The version of erwin Data Modeler must be the same as the Mart Sever version and all users should have the same client version installed. This issue is limited to the specific scenario where the erwin DM version and Mart versions can be different, e.g. 2020 R2 and 2020 R2 SP1. In general the versions of both erwin DM and Mart should be same to work together.
