SAP Error Message - Details

• Message type: E = Error

• Message class: CFD_REGISTRY_CHECK - Custom Fields: Messages for Registry Check

• Message number: 221

• Message text: Usage of DDIC suffix &1 in structure &2 for Include &3 cause DDIC errors

What causes this issue?

Usage of DDIC suffixes for Extensibility Includes is only possible if
the longest possible field name does not exceed 30 characters. Otherwise
this would cause activation errors in DDIC.
As the name of a custom field already consists of a prefix and a suffix,
the name length may exceed 30 characters when adding also the DDIC
suffix <(>&<)>1. This resulting DDIC suffix may be concatenated from
other DDIC suffixes when using group names for includes in your
structures.

System Response

The usage of DDIC suffix <(>&<)>1 in structure <(>&<)>2 for DDIC Include
<(>&<)>3 can lead to activation errors in DDIC as the name of a custom
field may exceed 30 characters.

How to fix this error?

Please remove or shorten the DDIC suffix depending on the used Extension
Include type:
Persistence Include (Business Context Registry): Resulting DDIC suffix
must not exceed the length of 3 characters
Transient Fields Include (Business Context Registry): Resulting DDIC
suffix must not exceed the length of 3 characters
Change Indicator Include (Business Context Registry): Resulting DDIC
suffix must not exceed the length of 3 characters
Union Fields Include (OData Registry): Resulting DDIC suffix must not
