Not Getting Data in SUP Preview MBO

Hi,

In SUP 2.1.3 i have created few MBOs using the BAPIs in SAP Backend system.

In one of the MBO when i am trying to preview the data from MBO by passing all the associated Input params, i am not getting any output.

Whereas in SE37 in SAP, when i execute the same BAPI by passing the same i/p params, i gets the data.

Please suggest me, what could be the reason behind this.

Regards,

Shrikant.
