# 28. Mutation: Save multiple "Notes", Batch operation

This mutation allows you to attach multiple Notes to a specified Field.

{% hint style="success" %}
The maximum amount of Notes to save is 25.
{% endhint %}

{% hint style="success" %}
Add the `uuid` attribute into the input to update the Note.
{% endhint %}

* A Note can be linked to the Field via its unique identifier `fieldUuid,`  to the associated SoilDataset via `soilDatasetUuid`, to the ZonesMap via `vectorAnalysisMapUuid`.
* The coordinate of the Note can be set using the `centroid` attribute, which requires defined `latitude` and `longitude` values. 
* The type of Note can be specified using the `type` attribute with acceptable values of `PLANNED` or `REAL`. 
* The description of the Note can be provided using the `comment` attribute. If the description needs to be multiline, the `comment` attribute should contain a string with newline characters `\\n` to separate lines. For example: `"First line. is here\\nSecond line is here.\\nThird line is here."`.
