Conversion of EAN code to SAP CODE

Hello,

I am trying to use a conversion setup through BD66 where I maninatin the EAN conversion from EAN to SAP code, this is not working also using a routine MATNE, I always get the same error message in the IDOC article description is missing.

I am using segment E1EDP19 - EXT MAT.IDNT nr.

This segment is not converting in the IDOC inbound orders from EAN 13 digit to SAP code.

Now I am not sure if the problem is with the way I am processing the IDOC with WE19, which field segments I should use or the conversion setup to activate this to work in the IDOC.

Any help or input is helpfull.

Thanks
