Enter a tabstrip number (>0)

What causes this issue?

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

System Response

Since incorrect or missing screen control data can lead to unidentified
program statuses and incorrect application data, the transaction is
terminated.

How to fix this error?

To resolve the problem, inform your System Administration.

Procedure for System Administrators

To enable you to use screen sequence control to specify a sequence of
tab pages for dynamic assignment, enter an ordinal number for each tab
page.
This ordinal number corresponds to the number of the tab page, although
neither the inital value nor the the increment are specified. To allow
any increment desired, the system does not check the ordinal number
entered with a maximum value. However, note that a maximum of up to 32
tab pages are possible per tab.
