In CDS ASSOCIATION except the base table, other tables are showing errors

Hi Experts.

Please find the code below. Which I am trying to activate. Its throwing an error so that I cannot use Association on 'EKPO' & 'EKKN' here. Whereas using Association between 'MARC' & 'EKPO' is not giving this error. I am unable to find why this is giving error. Please help me out in this case.

Note: I tried to learn about the Cardinality. But could find working examples for each one of them. And how the Cardinality is effecting the data in output?

    • Hi Horst,

      In that case, Association will not be helpful to replace a join related Views. And after creating few of them, still I didn't understood - How this could be implemented in such a scenario, where it works better that 'Joins' ?

      Can you please provide a detailed note if available in your knowledge.
