GRN POSTING FROM MM TO SUS

Hi,

While posting the GRN from MM to SUS am getting the below error in SUS:

An error occured within an XI interface: The reference to a source object via the object number is different than the reference via the GUID Programm: SAPLBBP_BD_API; Include: LBBP_BD_APIF39; Line: 175...

Pls advise.

Regards,

Manu
