DT157
- Append &: parent will be changed from & to & ?The SAP error message DT157 typically occurs in the context of data transport or when working with data dictionary objects, particularly when there is a change in the parent-child relationship of a data element or structure. The message indicates that the parent of a certain object is being changed from one value to another, which can lead to inconsistencies or issues in the data model.
Cause: Change in Parent Object: The error arises when an object (like a data element or structure) is being modified, and its parent object is being changed. This can happen during transport requests or when modifying data dictionary objects.

Transport Issues: If the transport request is not correctly set up or if there are dependencies that are not being handled
