Short Text
SAPoffice: Send new document
Functionality
This function module enables you to send a new document, which has not yet been created, internally and externally. During the send process the document is created, along with the attributes and content that are to be transferred.
Import parameters
DOCUMENT_TYPE
Default = 'RAW'.
Document class. All classes are possible except for folders ('FOL') and distributions lists ('DLI').
PUT_IN_OUTBOX
Default = ' '.
If this flag is activated ('X'), the newly created document is also placed in the outbox of the active user when it is sent.
DOCUMENT_DATA
This structure must contain the attributes of the document to be sent.
Table parameters
OBJECT_HEADER
This table must contain the document class-relevant data. For example, SAPscript documents store information here about forms and styles, Excel list viewer documents store, amongst other things, the number of rows and columns and PC documents store their original file names.
LINE
Requires class-relevant document information line by line.
OBJECT_CONTENT
This table must contain the actual content of the document.
LINE
Requires the content of the document line by line.
RECEIVERS
This table must contain the document recipients.
RECEIVER
Name of recipient.
Go through the sample program
REPORT  ztest_email                             .
DATA: OBJCONT LIKE SOLISTI1 OCCURS 5 WITH HEADER LINE.
DATA: RECLIST LIKE SOMLRECI1 OCCURS 5 WITH HEADER LINE.
DATA: DOC_CHNG LIKE SODOCCHGI1.
DATA: ENTRIES LIKE SY-TABIX.
DATA: NAME(15).
Fill the document
DOC_CHNG-OBJ_NAME = 'URGENT'.
DOC_CHNG-OBJ_DESCR = 'Read at once !'.
DOC_CHNG-SENSITIVTY = 'P'.
OBJCONT = 'Hey Altaf what are you doing !!!'.
APPEND OBJCONT.
OBJCONT = 'Lets go for movie !'.
APPEND OBJCONT.
DESCRIBE TABLE OBJCONT LINES ENTRIES.
READ TABLE OBJCONT INDEX ENTRIES.
DOC_CHNG-DOC_SIZE = ( ENTRIES - 1 ) * 255 + STRLEN( OBJCONT ).
Fill the receiver list
CLEAR RECLIST.
RECLIST-RECEIVER = 'LOGIN'. " replace with <login name>
RECLIST-REC_TYPE = 'B'.
RECLIST-EXPRESS = 'X'.
APPEND RECLIST.
