What causes this issue?

<DS:DE.FIELDNAME>Field</> &v3& of <DS:DE.TABNAME>structure</> &v2& is
allocated to attribute &v1& of <DS:DE.EPD_TYPEID>master data template
category</> &v4& as a reference.
The master data template uses this reference to convert the values of
the attribute. The values must be converted if you use the attribute as
a parameter and maintain it using external values. If the reference is
a data field for example, the system converts the parameter to an
internal data format.
You attempted to convert the attribute and the convertion did not work.
The reason for this is one of the following:
The reference is invalid.
You attempted to convert the attribute using an unsuitable value.

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