PRT Plant Conversion From Central Task List

Dear Experts

I have implemented BADI di_wps_convert_taskl in order to convert the task list work center based on the conversion rule (tcode Mebor).

It works fine when i assign the task list into the work order. The only problem is the plant for PRT does not converted.

Is there any other BADI that i need to implement in order to convert the PRT Plant data?

Thanks and Regards
