How To Fix UCMI019 - Doc.type &1: Document field "&2" must be hidden

SAP Error Message - Details

• Message type: E = Error

• Message class: UCMI - Messages for Breakdown Category, Item, Document Type, ...

• Message number: 019

• Message text: Doc.type &1: Document field "&2" must be hidden

What causes this issue?

In document type customizing on the <ZK>Document Field Options</> tab,
you can determine whether document fields should be hidden. If you do
this, note the following: If you hide an independent document field that
has no fixed value in the breakdown category, then all of its dependent
document fields must be hidden as well.
However, in document type &V1&, document field '&V2&' has not been
hidden, whereas, document field '&V3&' has. This is invalid, because '
&V2&' is dependent on '&V3&', and '&V3&' has no fixed value in the
breakdown category.
