After the update to the DocuWare version 6.9 the fixed select list cannot be assigned to a numerical field (integer field) any more.

Because of new implementations in DocuWare version 6.9 it should be avoided that values can be assigned to a field with different datatype.
This assignment led to various negative effects in former DocuWare versions (for instance problems with the autoindex workflow).
Therefore the product design decided that the fixed select list in now interpreted as text only and therefore cannot be assigned to a numerical (integer) field any more.

If you need to assign a select list to a numerical field, please use/create an external select list instead:
You can either configure an external database connection and define the used database field as an integer field.
Or you can create an external file connection and define the needed field to be interpreted as an integer field in the DocuWare Administration.
