Automated Configuration of Code List Mapping

Hi all,

my question is regarding ERP-C4C integration, currently code list mapping step.

We are wondering what "Consider C4C code list mapping" means for C4C upload afterwards.

Is it:

1. all C4C codes are cleared and only ERP codes are added to C4C code lists?
2. or are only existing C4C-ERP code list mappings overwritten?
3. what happens to not mapped code list values? are they removed at all (from C4C)?
4. what would happen in a delta load scenario, eg. like uploading mappings code list by code list?

So in short, does it only aim to code list mappings or even to pre-existing code list values in C4C?

The help says:

Consider C4C code list mapping: This denotes whether to consider existing code list mapping in the Cloud for Customer. If checked, the existing mapping information is not changed. Only those ERP codes that do not occur in the existing mapping are added. This is preferred during an upgrade.If unchecked, like during an initial load, only the code lists are considered and all existing mappings will be overwritten.
