As part of SAP Training,when you try to do a PGI to an SAP Delivery in our SAP SD Training Exercises or SAP MM Training exercises, the following error message pops-up “Number Ranges for Trans./Event type WL in year xxxx does not exist” Solution : This problem occurs because the SAP goods movement number ranges were not extended for the fiscal period. Go to Tcode [ OMBT ] and open up the groups in it. Select the group that contains the event type in question. In this case it is “WL” and hit enter. Insert a new Interval for the fiscal year that does not exist. In this case, 2011 does not exist yet. So, create a new entry for the same in the number ranges and save the transaction.
