SAP__Origin in bpmodata: field value too long

Hi all,

I'm consuming the BPM Odata service and it works really great.

Only I have this error: my OData parser is complaining that

The metadata constraints '[Nullable=false, MaxLength=16]' do not match the literal VHSLSDPOCI_DPO_00

This value is found in the payload of the Odata message in field <d:SAP__Origin>

I understand it has a value that is too long for the metadata definition of the field (max 16 characters in length).

The value above is made of hostname_SID_instNumber

Where is that value configured?

Thanks, Vincenzo
