• What is the cause and solution for SAP error message RU153 - Internal number assignment for object & (numbers are in critical area) ?

  The SAP error message RU153 indicates an issue with internal number assignment for a specific object, where the numbers are in a critical area. This typically occurs in the context of number ranges, which are used in SAP to uniquely identify objects such as documents, transactions, or master data.
  Cause:
  
  Number Range Overlap: The error often arises when there is an overlap in the number ranges defined for the object in question. This can happen if multiple number ranges are configured incorrectly or if the number range has been exhausted.

  Solution:
  
  
  Check Number Range Configuration:

  Ensure that the number ranges are correctly defined and that there are no overlaps or gaps.
