SAP Error Message - Details

• Message type: E = Error

• Message class: SDDIC_ADT_DDLA - Messages for Annotation Definition Design Time

• Message number: 047

• Message text: The recommended length should be '&1' (based on text length '&2')

What causes this issue?

Language dependent CDS annotations contain texts which are translated. A
CDS annotation is defined to be language dependent using the annotation
@LanguageDependency.maxLength.
For each language dependent annotation the annotation definition
specifies:
the maximum text length. Note that a text which is longer than the
maximum length may be truncated when it is stored.
the recommended length of the text within the bounds of the maximum text
length. The recommended length is calculated so that sufficient space
remains for translations. The recommended length is dependent on the
maximum text length:
Long texts (> 120 characters) - The recommended length is calculated so
that 30% of the calculated length can still be added to the text without
exceeding the maximum text length.
Medium texts (> 32 characters and <= 120 charactes) - The recommended
length is calculated so that 50% of the calculated length can still be
added to the text without exceeding the maximum text length.
Short texts (<= 32 characters) - The recommended length is determined
using a predefined matrix of values corresponding to the maximum text
length. These values are averages for the recommended length which
generally enable successful translations in common languages.
For example, the following definition defines a maximum text length of
60 characters for the values of the annotation @EndUserText.label and
recommends using maximum 40 characters thereof to always allow at least
20 characters (50% of 40) additional space for translations.
@LanguageDependency.maxLength: 40

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

EndUserText.label : String(60);
The recommended length is used to warn developers who specify a text
value for the annotation in their data definitions if the specified text
doesn't leave enough space for translations.

How to fix this error?

Use the suggested value for @LanguageDependency.maxLength in your
annotation definition to ensure that developers are warned correctly
when they specify texts that leave too little space for translations.
