BAPI_MATERIAL_SAVEDATA extensionin DEC type dump

Hi experts,

Under the SAP ERP 6.0 EHP7, we have this requirement added the 2 field( Dec type 9 length 2 point) in BAPI_TE_MVKE:

used the FM: BAPI_MATERIAL_SAVEDATA will have a dump, I guess it have the issue it is the type convert . because standard extension cant input the dec type , just input only char type.

and use the CALL METHOD cl_abap_container_utilities=>fill_container_c to convert the dec type. (the mothod can convert the QUAN type, it is okay work for BApi BAPI_SALESORDER_CREATEFROMDAT2 );

already config the 2 field in SPRO, checked the T130F.

But I got the dump when I run the code as below:

Could you give me the any idea? Thank you very much!

*------------------------------------------------------------------------------

SALES_ORG type VKORG CHAR 4 0

DISTR_CHAN type VTWEG CHAR 2 0

.APPEND type ZSMVKE_BAPI 0 0

ZZXJE type ZEZZXJE DEC 9 2

ZZXJESF type ZEZZXJESF DEC 9 2

And my code:
