How To Fix AQ225 - Check headers

SAP Error Message - Details

• Message type: E = Error

• Message class: AQ - Message texts for SAP Query

• Message number: 225

• Message text: Check headers

What causes this issue?

This query contains at least one statistic or ranked list where
currency amount fields are processed (i.e. amounts are converted to a
reference currency) and special headers are defined.
In the latest Release upgrade, reference currencies in statistics and
ranked lists are handled differently. Whereas the reference currency
was assigned for each statistic or ranked list before, it is now
assigned for each currency amount field. Therefore, the reference
currency must be displayed for each currency amount field (i.e. for
each column). In the case of standard headers, the reference currency
always appears in the second line of the column header. However, since
you have defined your own headers, automatic conversion by the query is
not possible.

System Response

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

How to fix this error?

Please check the headers of the statistics and ranked lists for this
query. When you compare your headers with the standard headers, you can
see where the query would insert the reference currencies.
If you also want to display the reference currency in the query list,
you must change your headers accordingly.
