How To Fix CM_REPORT_GEN023 - Value types do not match for symbol &1

CM_REPORT_GEN023 - Overview

• Message type: E = Error

• Message class: CM_REPORT_GEN - Report Generation

• Message number: 023

• Message text: Value types do not match for symbol &1

What causes this issue?

More than one value was determined for the parameter symbol &V1& during
the determination of the default parameter values (determination
function &V2&). These values were created with different value types.
The values cannot be output together with these different value types i
the output of multiple values for symbol &V1&.

System Response

Only values with corresponding value types are output during the output
of multiple values for symbol &V1&. Values without compatible value
types are not taken into account. This means, at least one of the values
does not appear on the report.

How to fix this error?

To avoid outputting multiple values of a symbol with different value
types, you can use a repetition group for the discrete explosion of
multiple values (D repetition group). The symbol is integrated into the
discrete repetition group. This way, every value type is treated as a
single value and not as a group of values of different value types.
