3742215 - API I_MaintenancePlanTP_2: mass Activate/Deactivate returns one summary message; details are written to application log

When using RAP EML to execute Activate or Deactivate for multiple Maintenance Plans via released BO I_MaintenancePlanTP_2, the response message table does not return one detailed message per Maintenance Plan.

Typical behavior:

• Only a single summary message is returned (for example message class EAM_MPLAN, number 035).
• Consumers expect item-level messages in the EML response but see only one message (often referring to the last plan or generic result).
• Detailed processing results are not available in the immediate EML message mapping.
