Description

When using the "toupper" function in a $filter expression, the JPA processor fails with a ODataNotImplementedException.

The same logic is already present for "tolower" in class ODataExpressionParser where it says

case TOLOWER:
return String.format("LOWER(%s)", first);

The attached .patch file contains an implementation for toupper.

 

Reasoning: SAPUI5 allows a "case-insensitive" filter, which uses the toupper() function internally.
