hi

<b>The following code may help you</b>

CONSTANTS: C_DOCTYP TYPE EDIDC-IDOCTP VALUE 'ZUSRDET01',Idoctype

C_SEGNAM TYPE EDIDD-SEGNAM VALUE 'Z1USRDET01', segmenttype

C_MESTYP TYPE EDIDC-MESTYP VALUE 'ZUSRDET'. message type

DATA: IT_ZUSR02 TYPE USR02 OCCURS 10,

IT_EDIDC TYPE EDIDC OCCURS 0,

IT_EDIDD TYPE EDIDD OCCURS 0,

WA_ZUSR02 TYPE USR02,

WA_EDIDC TYPE EDIDC,

WA_EDIDD TYPE EDIDD,

WA_Z1USRDET01 TYPE Z1USRDET01,

V_OCCMAX TYPE IDOCSYN-OCCMAX,

V_NBSEG TYPE I.

CLEAR WA_ZUSR02.

CLEAR WA_EDIDC.

• Save the message type and the basic IDoc type in the control segment.

MOVE C_MESTYP TO WA_EDIDC-MESTYP.

MOVE C_DOCTYP TO WA_EDIDC-IDOCTP.

• Retrieve the maximum number of segments in the basic IDoc type.

SELECT MIN( OCCMAX ) FROM IDOCSYN INTO V_OCCMAX WHERE IDOCTYP EQ C_DOCTYP AND SEGTYP EQ C_SEGNAM.

• Save the whole USR02 table content in the IT_ZUSR02 internal table.

SELECT * FROM USR02 INTO CORRESPONDING FIELDS OF TABLE IT_ZUSR02.

• Create a data segment for each line of IT_ZUSR02.

LOOP AT IT_ZUSR02 INTO WA_ZUSR02 .

MOVE-CORRESPONDING WA_ZUSR02 TO WA_Z1USRDET01.

CLEAR WA_EDIDD.

MOVE C_SEGNAM TO WA_EDIDD-SEGNAM.

MOVE WA_Z1USRDET01 TO WA_EDIDD-SDATA.

APPEND WA_EDIDD TO IT_EDIDD.

CLEAR WA_ZUSR02.

CLEAR WA_Z1USRDET01.

ENDLOOP.

• Count the number of data segments.

DESCRIBE TABLE IT_EDIDD LINES V_NBSEG.

• If the number of data segments exceeds the maximum allowed number,then display an error message.

IF V_NBSEG GT V_OCCMAX.

WRITE:/ 'ERROR'.

ENDIF.

CALL FUNCTION 'MASTER_IDOC_DISTRIBUTE'

EXPORTING

master_idoc_control = WA_EDIDC

• OBJ_TYPE = ''

• CHNUM = ''

EXCEPTIONS

ERROR_IN_IDOC_CONTROL = 1

well in your program u can read the control segment taht is exported by the FM master_idoc_Distribute from there u wil get the idoc number

or after running your program you can go to tcode WE02 there give basic type as your idoc type and extention if any

and execute that will give you list of idoc of that created . out of it the latest idoc created will be yours, double click on the idoc records and you can see how it is populated.
