Push data ECC to ewm

Hello,

I would like to push data from a z field I added to lips table from ECC TO EWM.

I enhanced the badi SMOD_V50B0001 and the method "EXIT_SAPLV50K_007" as described in the note 351303

There a sample code you need to implement which I did but I ma receiving an error when I try to activate the code.

"L_EXT-FIELD1" and "LS_DLV_ITM-DLV_ITM01" cannot be converted to each other in a Unicode system.

Did some one tried to apply this note?

do have a clue about this issue?

Best regards.

PS: the sample code is attached.
