MESSAGE MAPPING ISSUE

hi all,

I have prblm in msg mapping.

i have two strucutures one for proxy DT_Proxy and the other is IDOC CREMAS03.

In DT_Proxy, it has 10 fileds and these fields have to map with CREMAS fields in diff segments.

Source Structure:

DT_source:

LIFNR

NAME

KTOKK

LAND1

PSTLZ

BANKS

BANKL

BANKN

BKONT

KOINH

Target Structure:

CREMAS03

E1LFA1M : Segment for general vendor data (It is Root Segment)

LIFNR

NAME

KTOKK

LAND1

PSTLZ

-

E1LFBKM : Segment for bank details of vendor SMD (This Segment is as child to the abvoe)

LIFNR

BANKS

BANKL

BANKN

BKONT

KOINH

all are 1-1 mapping.

In source structure, only for LIFNR occurance as required, remaining are as attribute.

In target structure also LIFNR occurance as required but the remaining are as 1.

when i double click on segment names, it is showing as yellow nbut not mapped.

But i have assigned constant 1 to the segment fields of E1LFBKM and E1LFA1M .

All fields under the same segment are mapped to the target fields.

And i have obesrved that for the first 5 fields source field Display QUEUE is showing value but target field QUEUE is not showing any value only Empty.

now my boubt is why last 5 fileds not mapped.

Due to this the segment -

E1LFBKM is not created in the in the IDOC CREMAS03 in target R/3 system.

please help me

please dont hesitate to ask me any thinig

thanks in advance

regards
