3789388 - Error "Technical Name Is Already In Use Choose A Different One" While Creating A Custom Field In C4C

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."

SAP Cloud for Customer.

1. Log on to SAP Cloud for Customer.
2. Navigate to the required screen and start Adaptation mode.
3. Click on Add Field.
4. Click on Create Field.
5. Fill all the required details for the new custom field
6. Click on save
7. While saving the field the system displays the error "Technical name is already in use. Choose a different one."

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

This is a system-designed behavior 

To avoid such error, create custom fields using unique technical names that have not been used previously.
