How to fix this error?

- exclude the table from the conversion ( this is done in next activity
"<ZK>Consider analysis results</>" ) and manually adjust this table
after the conversion.
- change the assignment of the open item variant in table T001.
In any case, the table must be double-checked after the conversion, and
the customizing may have to be modified accordingly.
