SharePoint paths limitations are hard coded. The maximum path length is 260 characters. If that limit is exceeded, you get the SharePoint error 414. This article outlines how to avoid this error.
Minimum requirements: DocumentsCorePack v.167or higher
mscrm-addons products offer several default ways to shorten SharePoint paths:
1) We provide you with a default shortening to a maximum of 30 characters + GUID for each folder name.
SharePoint folder maximum length:
This setting cuts SharePoint folder names that are longer than a certain amount of characters.
2) We provide you with a default shortening to a maximum of 128 characters for each file name.
3) ShortIDs: We create a 6-characters ID alternatively to the well-known 36 GUIDs of Microsoft Dynamics 365.
It is recommended to activate ShortId to avoid the SharePoint error 414 you get because of the path limitations of 260 characters. With ShortId we create a 6-characters ID instead of the 36 GUID like you can see in the example below.
How to activate a ShortID for DocumentsCorePack
To create a ShortID for DocumenstCorePack simply navigate to Settings > DocumentsCorePack in your Microsoft Dynamics 365 application.
Here, please add/enable the following options:
Use short Documentation Logic
The setting in the figure below cuts SharePoint path automatically.

4) Use an alternative field for the generation of paths (e.g. instead of account name we can use a unique account number field)
For the SharePoint folder name attribute:
SPFolderNameAttribute: enittyschemaname;attributename|
e.g.: Account:ptm_name
Please note: Even though the creation of short paths is a very valuable feature, existing paths cannot be shortened anymore, unless very specific criteria are met. Manual interaction is always required.
