In POS Pro, finalizing certain documents may require entering your credentials (manager override) and/or capturing your signature. Such documents include Transfer Order, Transfer In, and Transfer Out, Purchase Order, Purchase Receipt, and Purchase Return as well as Adjustment Memo.
To finalize a document when acknowledgement is required:
Tap Finalize or Post in the document (depending on your document type). On tapping, the Acknowledgement dialog with several acknowledgement statements displays:
Select the required statement and tap Continue in the upper right corner of the dialog.
Then, if manager override is required, the Manager Override dialog displays. In the dialog, enter your username and password and then tap Log In.
Please note that to perform the manager override, you must be granted with the Allowed to acknowledge transaction right.
