How To Fix CNV_20100502 - Subgroups &2 of group &1 will have overlapping intervals

CNV_20100502 - Overview

• Message type: E = Error

• Message class: CNV_20100 - Messageclass for chart of account conversion

• Message number: 502

• Message text: Subgroups &2 of group &1 will have overlapping intervals

What causes this issue?

A group is unique if it only contains each subgroup and each value once.
Value intervals may not overlap each other.
The program found that after the conversion the group &V1& is not unique
any longer as the subgroups &V2& will have overlapping intervals.
This is due to the conversion of the two old intervals &V3& of the
subgroups into the two new intervals &V4&. These new intervals are
overlapping.
Old intervals: &V3&
New intervals: &V4&

System Response

The system only allows the display of ambiguous groups (not
maintenance).

How to fix this error?

To remove ambiguity, proceed as follows:
Resolve Set intervals by using the optional process tree activity
Alternatively
Call transaction KAH3 after the conversion
Choose Extras -> Ambiguity check. The system displays all of the groups
and values which occur more than once , and all overlapping values.
Remove these groups, values, and overlapping values by processing the
affected groups directly

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

If the standard hierarchy is affected, the compare function enables you
to compare the master data (Extras menu).

CNV_20100502 - Details

• The SAP error message CNV_20100502 indicates that there are overlapping intervals for subgroups within a specified group during a data conversion or migration process. This error typically arises in the context of data migration projects, particularly when using SAP's Conversion Tools or during the execution of specific data migration programs.
  
  Cause:
  The error occurs when:
  
  Two or more subgroups within the same group have overlapping time intervals. For example, if you have defined a subgroup with a time interval from January 1, 2023, to March 31, 2023, and another subgroup with a time interval from March 15, 2023, to June 30, 2023, this would trigger the error because the intervals overlap.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify Overlapping Intervals:
  
  Review the configuration of the subgroups within the specified group. Check the time intervals assigned to each subgroup to identify where the overlaps occur.
  
  
  
  Adjust Time Intervals:
  
  Modify the time intervals of the subgroups
