Regarding ODATA Filter Any Vs All

Hi Team,

We are building an API to expose our account data for entities using ODATA REST API.
One of our downstream system who wants to consume our API wants to filter data for all Internal Accounts only.

The Query used is $Filter=accounts/all(account: account/Type eq 'Internal')
They get all the Entities with accounts that have 'Internal' but for few missing entities. One such missing entity in output payload is "EntityId": 140630.

The only difference between this entity '140630' and other entities that make up to the payload is that, this entity has accounts that belong to both types 'Internal and External'.

But the expectation is that downstream wants all entities that have accounts with type 'Internal' invariably whether the entity has only Internal accounts or both (Internal and External).

Based on our initial analysis, ODATA 'All' filter considers entities that have only Account/Type that has 'Internal' and skips entities with accounts that have both 'Internal' and 'External'.

With 'Any' Filter, entities that have account type 'Internal' + entities that have account type 'Internal' and 'External' are fetched. In this case we see the payload having Entity 140630 with accounts both Internal and External. But as per requirement, the downstream system should not be exposed with 'External' accounts.

Need support to write a fitting ODATA Filter that brings Entities that contains internal accounts. Whether they have only internal accounts or have both internal and External accounts.

From the sample payload provided below
the filtered output should bring entities
"EntityId": 140278, and accounts (Only have internal accounts)
"EntityId": 440365, and accounts (Only have internal accounts)
"EntityId": 140630, and accounts "Id": 228643,"Id": 228647, (Only internal accounts from the list of accounts they have)

Any directions to achieve the above requirement will be much appreciated.

The json payload with out any filter looks like

Start by reviewing the OData any/all filter semantics against the query and sample payload in the issue. Confirm whether the requested result is expressible with the API's supported filters; done means providing a validated filter or documenting that the requirement needs a different API response shape.
