>>> PLEASE READ THE REPORT DOCUMENTATION OF THE REPORTS MENTIONED ABOVE <<<

XPRAs are application reports that run at the end of an upgrade.
Most XPRA reports have a report documentation that explains what
the report does and how errors can be corrected.

Call transaction se38 in the SAP system, enter the report name,
select 'Documentation' and click the 'Display' button.
>>> The problematic XPRAs are mentioned in messages of type PU132 above <<<

any one can you please help me, what are the possibilities  lock/unlock  during the upgrade.

Thanks & regards,
