How To Fix DH821 - Interval is sorted according to internal representation

SAP Error Message - Details

• Message type: E = Error

• Message class: DH - DD: Messages for search helps

• Message number: 821

• Message text: Interval is sorted according to internal representation

What causes this issue?

The data is displayed (external representation) and stored (internal
representation) differently for this data type.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

The value range is interpreted in internal representation. This means
that the lower and upper limits are converted to internal
representation prior to selection. Contiguous areas in external
representation need not be contiguous in internal representation.
If you do not know how the data is represented internally, enter single
values instead of value ranges for the restrictions.

• What is the cause and solution for SAP error message DH821 - Interval is sorted according to internal representation ?

  The SAP error message DH821, which states "Interval is sorted according to internal representation," typically occurs in the context of data selection or filtering operations in SAP systems, particularly when dealing with ranges or intervals in selection criteria.
  Cause:
  This error usually arises when the intervals or ranges defined in a selection screen are not sorted correctly according to the internal representation of the data. In SAP, data types have specific internal representations, and if the intervals are not aligned with these representations, the system cannot process them correctly.
  Solution:
  To resolve the DH821 error, you can take the following steps:
  
  
  Check the Selection Criteria: Review the selection criteria you have defined. Ensure that the intervals are specified correctly and that they are in the expected order.
  
  
  Sort the Intervals: If you are using multiple intervals, make sure they are sorted in ascending order based on their internal representation. For example, if you are working with date fields, ensure that the dates are in chronological order.
  
  
  Data Type Consistency: Ensure that the data types of the fields you are working with are consistent. For example, if you are filtering dates, make sure all date formats are the same.
  
  
  Use Valid Ranges: Ensure that the ranges you are using are valid and do not overlap in a way that would cause confusion in sorting.
  
  
  Debugging: If you have access to debugging tools, you can step through the code to see where the error is being triggered and examine the values being processed.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance related to the transaction or report you are working with.
