Characteristic IDoc processing Problem CHRMAS

Hi,

I am creating characteristic (CT04)using IDOC with message type CHRMAS and standard function module (IDOC_INPUT_CHRMAS).

characteristic created successfully with Create Idoc. But while trying to update the characteristic through Idoc, the Basic data description field and the text fields become empty though it processes successfully.

I am passing values for the description tab for language EN and Z1.

Passing the following values in both create and change :

E1CABNM-->

ATNAM

ATFOR

ANZST

ATKLA

ATMST

FUNCTION

E1CABTM-->

ATBEZ

SPRAS_ISO

Have you faced this type of problem? Any suggessions?

Regards,

Tanmay
