The length was modified in the latest releases of our addon, having a maximum length of 50 characters.
The log table is created with a length of 50 characters for the ItemCode. But the add-on only checks if the field is present or not, and if it is not present, it creates it with that length.
If the table already exists previously, it has been left with the original length of 20 characters. In this case, you can directly edit the field length and set it to 50, from the UDF definition:
Or, another option, is to delete the UDO and UDT tables from the logs and restart the add-on. There, they will be created again but with the current definition.
Take in mind that, by doing this, all the logs will be erased, which is also good to do from time to time so that they are not too large.
