  SAP Error Message:
  WA899 - Specify a time period to the next read access
  
  
  Cause:
  This error occurs when a program or transaction expects a time period to be specified for the next read access, but no such time period has been provided. Typically, this happens in scenarios involving data buffering, polling, or scheduled data reads where the system needs to know how long to wait before the next data retrieval or read operation.

  When does it occur?
  
  During data buffering or polling operations.
  When using function modules or programs that require a time interval for repeated data reads.
  In custom developments or standard SAP programs that manage timed data access.
  Possibly in scenarios involving RFC calls, batch jobs, or data synchronization where timing control is necessary.
