Dear Ms. Rebecca
I assume you need to modify the document numbers in Inventory including (Adjustment, Transfer, Variance, Production and In-Transit Transfer).
I assume you could change the prefix along with resetting the serial to one. For instance, lemme assume that your adjustment document numbers have reached (00000000000000109). From Inventory Control setup, set the next document number under Adjustment to (ADJ00000000000001).
This ensures splitting the historical inventory documents from the current ones. On the other hand, I don't recommend changing the historical inventory transactions.
Best Regards,
