Add optional import parameter to an EXISTING Z function module.

[manoj_goyal2]

Hi Guys,

I want to add an OPTIONAL IMPORT parameter. What are the things I need to take care to change and activate the FM, so that the changes does not effect the other programs calling this Z function module.

Thanks,

since you are going to make it an optional parameter, you will have no problem there. However, you have to make sure that, upon calling this function module, the functionality will not change for the other objects by introducing a new variable.

What to do?

Just add this new parameter, make it optional (mark checkbox) and do the coding.

Adding one more point,

While raising exceptions to your ootional parameter make sure that

For example XINT is optioanl paramter then

if NOT xint is initial.
   " then raise your exception
endif.
