HTTP status code: 501 (Not Implemented)

BPM error code: empty

If you have a BPM error code, see the corresponding documentation.

Reason

The user tries to execute the unsupported operation. This could have the following reasons:

  • $filter expression contains an unsupported property for filtering in the entity set. Example:

    GET /bpmodata/processes.svc/ProcessCollection?$filter=Subject eq 'test'

  • $filter expression contains an unsupported operator for filtering in the entity set. Example:

    GET /bpmodata/processes.svc/ProcessCollection?$filter=StartDate gt datetimeoffset'2014-09-01T00:00:00Z'

  • OData query option is not supported for the entity set. Example:

    GET /bpmodata/processes.svc/ProcessCollection?$orderby=Status

Solution

To correct the problem, choose the corresponding solution:

  • Specify a supported property in $filter expression. Example:

    GET /bpmodata/processes.svc/ProcessCollection?$filter=Status eq 'IN_PROGRESS'

  • Specify a supported operator in $filter expression. Example:

    GET /bpmodata/processes.svc/ProcessCollection?$filter=StartDate ge datetimeoffset'2014-09-01T00:00:00Z'

  • The unsupported query option cannot be used.
