Validation error in BODS job while calling BAPI_MATERIAL_SAVEDATA

Hi,

I am trying Create MATERIAL in SAP by calling BAPI_MATERIAL_SAVEDATA BAPI from BODS. The job worked fine for basic view. But when I have added addition flows, and assigned all the parameters m getting the error at the time of job validation

Validation error nrdm function <cannot parse expression. for the call to function , cannot convert parameter number <534> to type <varchar>. provide a parameter of the correct type.. (bodi-1112351)> (bodi-1111191)

I tried looking into the values that I have passed for each parameter but that looks fine.

Can someone help on this please
