What is SAP's recommendation for data filtering when using IDoc communication?

Use a condition filter in the middleware to ensure other integrations are NOT impacted and all filtering logic can be maintained in one central place

Use custom BAdis to ensure other integrations are NOT impacted by SAP Sales and Service Cloud integration

Use the standard filtering objects in the ALE distribution model. If this is NOT sufficient, use the IDOC_CREATION_CHECK BADI

Use the change pointers BADI, IDOC_DATA_MAPPER. If this is NOT sufficient, use the IDOC_CREATION_CHECK BADI
