CNV20305062 - Overview

• Message type: E = Error

• Message class: CNV20305 - Messages for conversion packages in CO

• Message number: 062

• Message text: Im target CoAr &1, no.rg. &2 overlaps in area &3 ( from CoAr &4 )

What causes this issue?

Documents from CoAr &V4& are converted so that they are stored in
target CoAr &V1& in number ranges &V2& in area &V3&.
This area overlaps with another area, in which other documents are
stored. For details on this second area, see the next message in the
log.

System Response

When simulating the document conversion, the system has found that
certain document intervals overlap. As intervals must not overlap, the
control tables for document conversion have to be adapted accordingly.

How to fix this error?

Using the next message, check in which area the numbers overlap and
adapt document conversion (using the maintenance view for tables
CNV_NRIV_O and CNV_NRIV_N) so that all overlaps are removed.

This error indicates that there is an overlap in the target cost allocation (CoAr) for a specific region (rg) in the specified area.
  
  Cause:
  The error arises when:
  
  There are overlapping entries in the target cost allocation (CoAr) for the specified region.
  The data being migrated or converted contains conflicting information that violates the rules of unique allocation in the target system.
  The source data may have been incorrectly structured or contains duplicates that lead to this overlap.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Data: Check the source data for the specific cost allocation entries. Look for duplicates or overlapping entries that may be causing the conflict.
  
  
  Adjust the Target Configuration: Ensure that the target configuration allows for unique entries in the specified area and region. You may
