It worked for me when I tried it.
To set up the statistical unit in GL90A or 90B, edit the account and in the unit field, enter any text which will be used as the unit label. Before trying to use this stat unit in Receivables, first make sure that it is working when you enter a journal entry batch in Ledger. When you select the GL account, do you see the unit label and field on the right-hand side of the entry detail screen?
If so then open Receivables 90A. Create a new invoice for any customer and on the detail screen, enter the same GL account. You should see the statistical unit label and field appear to the right of the amount field.
If a cash batch is created and a miscellaneous entry (ie a blank customer number) is done, then the detail screen here also correctly displays the statistical unit for that GL account, to the right of the amount field.
If an adjustment entry is created for that GL account, the statistical unit will also displayed here, to the right of the base field.
If you create or edit a distribution code in AR90A for that GL account, you can see the stat unit field here, and even enter a default value of the unit (and amount too) for whenever this distribution code is selected for the invoice.
If you create or edit a distribution set in AR90A, associated GL accounts or distribution codes will also display stat units and allow entry of default values.
If it doesn't work for you, could you indicate the steps you are following and where you expect to see the statistical unit and are not? If in one of the locations above, it may be that the programs are not installed correctly, or perhaps the statistical unit is not set up for the GL account.
