  The SAP error message CRM_PML156 indicates that there is a performance issue related to the transport of a mail form in the SAP Customer Relationship Management (CRM) system. The message specifies that the transport of the mail form took a certain amount of time (in milliseconds), which may be longer than expected.
  Cause:
  
  Network Latency: High latency in the network can cause delays in the transport of mail forms.
  System Performance: The performance of the SAP system itself may be suboptimal due to high load, insufficient resources (CPU, memory), or other performance bottlenecks.
  Mail Configuration: Incorrect or suboptimal configuration of the mail system (e.g., SMTP settings) can lead to delays.
  Mail Form Complexity: If the mail form is complex or contains large attachments, it may take longer to process and send.
  Background Jobs: If there are many background jobs running simultaneously, it can affect the performance of the mail transport.
  
  Solution:
  
  Check Network Performance: Monitor the network for latency issues and ensure that the connection between the SAP system and the mail server is stable and fast.
  System Monitoring: Use transaction codes like ST03N, ST06, or SM66 to monitor system performance and identify any bottlenecks. Consider optimizing the system resources if necessary.
  Review Mail Configuration: Check the SMTP configuration in transaction SCOT. Ensure that the settings are correct and optimized for performance.
  Optimize Mail Forms: If possible, simplify the mail forms or reduce the size of attachments to improve processing time.
  Schedule Background Jobs: If there are many background jobs, consider scheduling them during off-peak hours to reduce the load on the system during peak times.
  Increase Timeout Settings: If the transport is consistently taking longer than expected, consider increasing the timeout settings for the mail transport.
