Fix 225MB result size limit in Flow Action Details sync with batch processing

[Copilot]

The Admin | Sync Template v3 (Flow Action Details) flow fails in environments with ~90K flows, exceeding Power Automate's 225MB aggregated result size limit. The flow attempted to retrieve all flows in a single Dataverse ListRecords call with minimumItemCount: 100000.

Changes

• Added environment variable admin_FlowActionDetailsBatchSize (default: 5000, range: 1000-10000)
• Modified query actions to use $top parameter for batch processing:
  • Flows_to_iterate in Get_flows_to_update scope
  • Flows_to_iterate_with_specialty_flags in Clear_Specialty_Flags scope
• Updated pagination policies to respect batch size parameter

Implementation

{
  "parameters": {
    "$top": "@parameters('FlowActionDetailsBatchSize (admin_FlowActionDetailsBatchSize)')",
    "$filter": "admin_flowdeleted ne true and admin_inventorymyflowactiondetails eq true..."
  },
  "runtimeConfiguration": {
    "paginationPolicy": {
      "minimumItemCount": "@parameters('FlowActionDetailsBatchSize (admin_FlowActionDetailsBatchSize)')"
    }
  }
}

The flow now processes flows in batches, clearing the admin_inventorymyflowactiondetails flag after each batch. Multiple runs handle the full dataset without exceeding size limits.

Impact

• Environments with <10K flows: Single run, no behavior change (default 5000)
• Environments with 90K flows: ~18 runs at default batch size, each <50MB
• For large environments: Set batch size to 2000-3000 for optimal performance

Files Changed

• AdminSyncTemplatev3FlowActionDetails-7EBB10A6-5041-EB11-A813-000D3A8F4AD6.json (+14/-4 lines)
• admin_FlowActionDetailsBatchSize/environmentvariabledefinition.xml (new)
• docs/SOLUTION-FlowActionDetails-BatchSize.md (new, configuration guide)

<issue_title>Reopen #10256</issue_title>
<issue_description>Since I'm unable to reopen, I'd like to find a permanent and supported fix for #10256 where Flows_to_iterate fails due to the # of flows in the environment, which is approaching 90,000.</issue_description>

<agent_instructions>Analyze and provide a permanent, supported fix for the failure in Admin | Sync Template v3 (Flow Action Details) where the Flows_to_iterate action exceeds the max aggregated results size (error >225MB) in an environment with ~90,000 flows. Identify the root cause and recommend a scalable approach (pagination, batching, filtering, or redesign) so the flow can handle very large environments without hitting the result‑size limit.</agent_instructions>
