We started configuring our new solution for our project on Wednesday. Company Codes and Plant Codes are critical underpinnings of the whole SAP installation for a company, and one has to get these right to make the system work. I can write a book about the SAP Plant Code and how it should be set up (but I will not do that here !). The Plant Code is where lots of equipment are co-located – that the company uses to make stuff or to run its business. How many to create, or where to draw the lines for separate Plant Codes is sometimes hotly debated !
