Outbound file

Question

Hi ,
  i need to send the SAP data to liberty through an outbound interface flat file . The file has 3000 characters and in that they are only few fields from SAP has to be filled and the rest of the fields  has to be filled with spaces in between the SAP fields . I am taking output table and in that i am filling required fields from SAP and the rest of them as a Filler varaibles in between but the output table declaration comes out too big,Please let me know if there is any other approach to follow.
Thanks,
Makks.

Answer 1

I don't think you have to define an internal table with all the filler fields if you are sure that SAP is not going to be the source for those fields. You can deal with it in different ways.
option 1.
Declare only one field for the entire free space.
data: begin of itab occurs 0,
        field1 ....,
        field2 ....,
        myspace1(1000),
        field3.....,
        myspace2(1000).
data: end of itab.
Here we are combining all the blank fields into a single field even though for the receiving system, it may be 20 fields. So myspace1 if just one field of your internal table with 1000 spaces, your receiving system will see it as 20 fields with spaces.
option 2:
Declare an internal table with just the fields you fill in from SAP. When you are transferring the record to unix using 'TRANSFER', you move the individual fields to the corresponding offsets of a 3000 long string.
data: v_string(3000).
data: begin of itab occurs 0,
        field1...
        field2....
        field3...
data: end of itab.
loop at itab.
  clear v_string.
  move: itab-field1 to v_string+0(xx),
        itab-field2 to v_string+50(xx),
        itab-field3 to v_string+2525(xx).
  transfer v_string to file.
endloop.
