Issue in uploading key mapping using DTIMPORT

Hi,

I am trying to upload key mapping using data import in MDG by implementing file converter badi with input file of type .csv. Below are the challenges I am facing.

1. In the GET_DATA method of the file converter badi, what is the structure to map the file data ? I have used the structure  mdg_t_get_matching_easy_bs but it is now working.

2. Another issue I am facing is, in the method GET_INBOUND_STRUCTUREof teh standard class CL_MDG_UPLOAD_IDM, variable MV_INTERFACE and MV_METHOD are not filled.Because of this DTIMORT is giving runtime error before coming to fiel converter badi.

3. In the key mapping configuration, do we need to mention the name space?

If anybody has implemented file converter badi for key mapping, please provide the details.

Appreciate your help.

Regards

Shoban
