• What is the cause and solution for SAP error message RT871 - Number Range Buffer: number of free entries ?

  The SAP error message RT871 indicates that the number range buffer for a specific number range object has run out of free entries. This typically occurs when the system has exhausted the available numbers in the buffer for generating new document numbers, which can happen in high-volume environments or if the number range is not properly configured.
  Cause:
  
  Exhausted Buffer: The number range buffer has been filled up and there are no more free entries available for allocation.
  Configuration Issues: The number range may not be configured to allow for sufficient entries, or the buffer size may be too small for the volume of transactions.

  Solution:
  
  
  Increase Buffer Size:
  
  You can increase the size of the number range buffer. This can be done in the transaction code SNRO (Number Range Objects).
