PROJ-.####
PROJ-.{customer_name_naming}.-.####

This serial number contain value of this field customer_name_naming

After save the project, if you change the value of this field customer_name_naming then error will come. that’s is correct.

Project Code is the ID of record. After save the record, you can’t change the ID

so in this case I cant change the project type from internal to external

If the fieldname of Project Type field is customer_name_naming then you can’t change it
