How To Fix J3636 - Inconsistency in data flow mode. Transfer terminated

J3636 - Overview

• Message type: E = Error

• Message class: J3 - Dialog Messages for Data Pool Entry Transactions

• Message number: 636

• Message text: Inconsistency in data flow mode. Transfer terminated

What causes this issue?

The transfer was terminated due to incosistencies in the mode of the
data flow.
The mode was not uniform for the transferred records. You do not
necessarily need to specify a mode for every record. Note that at least
one mode has to be specified in at least one record. This will then
serve as a global mode for all the records. However, if you specify
modes in more than one record, they must all be the same mode.
&SYSTEM_RESPONSE& (EDT only)
Transfer terminated.
&WHAT_TO_DO& (EDT only)
Maintain a mode(s) in accordance with the above description and
retransfer the data.

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

This is a regulatory reporting message.

  Causes:
  
  
  Configuration Issues: There may be inconsistencies in the configuration settings for the data flow, such as incorrect settings in the data source, data target, or transformation rules.
  Data Model Changes: Changes in the underlying data model (e.g., changes in fields, data types, or structures) that are not reflected in the data flow configuration can lead to this error.
  Incompatible Data Types: Mismatches in data types between the source and target systems can cause inconsistencies.
  Missing or Incorrect Mapping: If the mapping between source and target fields is incomplete or incorrect, it can lead to data flow
