Procedure (step-by-step) to change a transformation function

Question

Hi,
Has someone wrote some procedures to describe how to change a transformation function when the system is running? For example: what are the steps to do when i want to add a column in the supplemental log for a table and use it in a transformation function? I must change the transformation function only when all the LCRs that don't have the new column as been processed. What are the exact steps to do this without headaches.
Thanks.

hi,
We can create FM in Function-builder for that one we work with SE37.
for declaring fields choose option IMPORT of function builder, under that define
field vbeln type <refarence table-field > and provide value for it type , check the mandatory option.
posnr type < refarence table-field>and check the optional option.
file path type c . here u choose the proper dictionary datatype.
next Select the option EXPORTING.
file type ( specifies the same type as mentioned above)
First u need to create a function group
use SE37 goto--> function groups --> create group
Use this FG to create a FM
Import parameters
VBELN type VBELN Optional = " "
FILE TYPE LOCALFILE Optional = " "
POSNR TYPE POSNR Optional = "X"
There will be no export parameter .
within the FM use WS_DOWNLOAD , GUI_DOWNLOAD to crete the file on the path specified.
write the code
activate the top include & the FM together
go through this link,which ll give you detail about creating a function module
