Extending a standard fetch BAPI (for equipment) in SAP Work Manager application

Hi Experts,

I am trying to extend a particular fetch BAPI (EquipmentFetchBapi) to include a custom functionality, but I couldnt find any parameter in the config panel to set so.

In the config panel, I see that the BAPI class - com.syclo.sap.component.equipment.bapi.EquipmentFetchBapi has been assigned under the parameter group "BAPI_WRAPPER" and the parameter value is set to the FM under ECC.

Now, when the workOrderFetchBapi calls the equipmentFetchBapi to get the data from ECC, my requirement is to call the custom class (CustEquipmentFetchBapi) instead of standard one.

I see that the workOrderFetchBapi doesn't make use of Object factory while calling equipmentFetchBapi and that's why parameter configuration at ECC side wont be helpful.

Is there any other way I can enhance the equipmentFetchBapi/workOrderFetchBapi  so that the workOrderFetch bapi will call my customEquipmentFetchBapi?

Any help will be appreciated.
