How To Fix SV090 - The compare operator is only permitted for character fields

SAP Error Message - Details

• Message class: SV - View Maintenance: Customize Messages

• Message number: 090

• Message text: The compare operator is only permitted for character fields

What causes this issue?

In the definition of the selection condition, you have, for one field,
used a compare operator, which can only be used for character fields
(for example, "CP" search). The current field is not a character field.
The internal system representation of the field contents therefore
deviates from the external representation on the screen. Comparisons,
which assume that internal and external respresentation of the field
contents are identical, cannot be performed. The specified selection
cannot therefore be evaluated.
