Errors while building the relation ship between Direct connected module and imported excel

Hi SurendraD ,

From your description, it appears that you are encountering errors when trying to establish these relationships. Here are some steps that may help resolve the problem:

1. Ensure that the columns you are trying to relate to have matching data types and that both columns have corresponding values. Mismatched data types or missing values may prevent the relationship from being established.
2. You are working with a complex data model, make sure that the structure of your model supports the relationship you are trying to create. Refactoring the model or using bridging tables can resolve relationship issues. For more insights on data model relationships, this article may be helpful:
