Symptom
When creating a new custom field through Adaptation in C4C, the system displays the error message - "Technical name is already in use. Choose a different one."
Environment
SAP Cloud for Customer.
Reproducing the Issue
- Log on to SAP Cloud for Customer.
- Navigate to the required screen and start Adaptation mode.
- Click on Add Field.
- Click on Create Field.
- Fill all the required details for the new custom field
- Click on save
- While saving the field the system displays the error "Technical name is already in use. Choose a different one."
Cause
The error occurs because the entered technical name has been already in use for an existing custom field in the system.
In C4C, technical names are stored in the backend and acts as a unique identifier for the field and must always remain unique.
If a technical name has already been used for a field, the same name cannot be used again for another field, even if the field is created in a different Work Center
Resolution
This is a system-designed behavior
To avoid such error, create custom fields using unique technical names that have not been used previously.
