I try to delete a line record on my custom module but got this error quite often,  
deleteExtraFields error -4 ‘table\_name\_prefix’ is to long

 ![image](https://www.dolibarr.org/forum/uploads/dolibarrorg/original/2X/7/7cc89fad57eb1f3cf6323f0b967fc7148fab6e7e.png)  
any config needed to add max. length of table name? or anyone know about dolibarr max. length for table name? so I’ll rename the table to suit the rule. Thanks.
