Enable the integration between Power Platform and SAP to announce changes in SAP to Power Platform asynchronously and so not in realtime, without coupling the both systems. A good design will take in consideration the existing design related to SAP (see image below).

...

Context and Problem

1. Current architecture implying a front door (micro-service) is mandatory. Direct access to SAP is not allowed.

2. No current integration between Power Platform and SAP. Power Platform is a SAAS in the public Internet even if it’s in the backbone of Microsoft.

3. For now, there is only a one-way communication, from SAP to Power Platform. Data transfered from SAP is not considered as confidential.

4. Data volume is not substantial : about 2 thousand records could be affected in Power Platform. Not a case of intensive computing and long-running functions.

5. Hybrid scenario is highly recommended regarding the current architecture related to SAP and the willing to upgrade the latter to Hana.

Execution of the validation method

public ResultValidation ValidateExecutionContext(string key)
{
      if (string.IsNullOrEmpty(key)) return null;
      var result = new ResultValidation();

      if (key.ToLower() != Constantes.KNA1.ToLower()) { return result; }

      result.executionContext = EnumExecutionContext.UseCase.KNA1;
      result.validated = true;
      result.key = key;

      return result;
}
