how to remove some characters from a source value in SAP BODS

Hi

I'm extracting the data fro EQUI table from SAP ECC into Oracle By using Data Service . I would like to remove two characters from the source value while data is extracting from ECC to Oracle (Template Table)

The source data is like below

EQUNR                OBJNR

123                       IE00000123

I want to remove IE from the OBJNR field source value and like the target data like below

EQUNR                OBJNR

123                       00000123

How can i achieve this in SAP BODS

Please let me know

Thanks
