In my Canvas App I want to create new record on relationship table
I have Table A and Table B which have Many-to-Many relationship, when this relationship was set new table was created:
In relationship table name I see name of new table, but:
A) I can't see this table on Tables-->ALL in CDS
B) I can't add this table as a dataousrce in Canvas App
Is there any way to access this entity?
Anyone had same issue?
In CDS you can’t access the junction table created using the OOB method for creating relationships. However, you can create your own junction table and there are good reasons for doing this such as adding fields that are appropriate to that table and not the other two.
@Drrickryp thank you for answer, So how can I tie my records if I cannot access a table (and without creating new table) I figured out there must be a way to do this - otherwise the many-to-many relationship would be useless, right?
For a complete explanation of how to work with the OOB solution for many to many relationships, see https://powerapps.microsoft.com/en-us/blog/relate-records-in-many-to-many-relationships/
For an example of how to work with relationships in PowerApps dataverse follow this exercise: https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/northwind-install .
The OOB many to many relationship that CDS uses has advantages and disadvantages. In my mind, one of the biggest is the inability to add fields to the junction table. I am an old school database designer and have chosen to manually create the junction tables in my CDS based apps just as I had for years in developing MS Access database solutions.
