Extract VRGNG field from COEP/COBK tables

Hi All,

I am trying to extract Cost Center Actual data using 0CO_OM_CCA_9 datasource. It brings data from COEP/COBK tables. 

I need to have VRGNG (CO Business Trasaction) field shown in my report which is in the source tables.  The above standard extractor doesn't bring this field directly, but it is using this field doing some lookup in table COSP_VTYPE and converting into multiple BI fields like MEASTYPE, VTSTAT, VTDETAIL and VTYPE.  But I need to show the value of this field as in ECC table in my report.

Can anyone tell me how do solve this? Is enhancing the CCA_9 extractor is my only option?  As the VRGNG field is present in the source table of this extractor, do I have to write any code to bring this value to BI or not necessary ?

Thanks in advance.

Ram.
