This is because, in a sufficiently complex system you will have changes to Customer's possibly affecting Orders, Inventory, Payables... You can then have changes to Inventory possibly affecting Orders, Customers, Receivables... You can then have changes to Receivables, affecting Orders, Customers, Inventory... You can then have changes to Sales Reps affecting Customers, rders,Payroll... I did say "if you can arrange it" - I understand it may not always be ossible. Whenever you get a deadly embrace, examine the two programs nvolved and see if you can reorder the READU's. If you can, then that ill prevent the problem happening again.
