Title
CategoriesName
ItemCode (this will be for auto generate)
i use
concat('TDS-',triggerBody()?['CategoriesName']?['value'],'-',triggerBody()?['ID'])
it's working
but i change my plan to use Only First 3 letters of my CategoriesName
example: if CategoriesName Is TABLES so i need To input in the code Only TAB
