error in SABRIX conection

Hi,

We Have establisied SABRIX connection with SAP in our development server. it worked fine . When the same is moved to the quality server , the following error occured while testing the RFC 'RFC_CALCULATE_TAXES_DOC'. The error is 'Error in RFC_CALCULATE_TAXES_DOC: null' with errorcode '0001'. We have checked all the configurations from SAP side and found those are transported succesfully. I could not debug the RFC as no code is there inside the RFC.however the other two RFCs are successful.

Has anybody faced the same situation before? Has the error anything to do from SABRIX side.

Regards,

Jaydip
