Message text: Data type of Data Dictionary (DDIC) type '&1' does not match
The current BRFplus data object is bound to Data Dictionary (DDIC)
element &v1&. However, the system has determined that the type of the
data object and the DDIC element do not match. The deviation that has
been determined can relate to any of the following aspects:
Data object type (element, structure, table)
Elementary type of one or more fields in the data object (for example,
number, text, boolean, and so on).
This kind of problem is usually caused by changes done in the DDIC after
the binding relationship has been established.
The object cannot be activated.
Find out which version of data modeling is adequate for the use case you
are dealing with. Depending on your findings, proceed according to one
of the following alternatives:
BRFplus data object type suits better: Bind the data object to a DDIC
element that matches the current data object type. You can also decide
to remove the binding relationship and define the data object by means
of BRFplus.
DDIC element type suits better: Refresh the binding of the data object
so that it reflects the current DDIC type. Do not forget to check all
usages of the data object to make sure that no referencing object relies
on the data type that was in effect before.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

FDT_CORE398
- Data type of Data Dictionary (DDIC) type '&1' does not match ?The SAP error message FDT_CORE398 indicates that there is a mismatch between the data type defined in the Data Dictionary (DDIC) and the data type expected by the application or function module. This error typically arises in scenarios involving data mapping, especially when using the SAP Field Data Tool (FDT) or similar data handling mechanisms.
Cause: Data Type Mismatch: The most common cause is that the data type defined in the DDIC for a particular field does not match the data type expected by the application. This can happen if: The field in the DDIC has been changed (e.g., from CHAR to NUMC) but the application code has not been updated accordingly. There is a discrepancy between the data types in different systems (e.g., development vs. production). The data type in the FDT configuration does not align with the DDIC definition. Incorrect Mapping: If you are using a mapping tool or configuration, the mapping might be
