Default parameter in FM

Former Member — Wed, 23 May 2007 09:51:06 GMT

Hi,

i'm creating a Function module in SE37 and i would like to have a default value for my IMPORT parameter (import tab) which is a date that should be set to the actual date - 3 days.

I can't specify sy-datum - 3 and it does not recognize any variable i declare in the source tab.

Is there a way to do this ?

Hi,

in your FM , check if your parameter is empty, if it is assign actual date - 3 in in before processing!

Hi Tomislav,

Instead of trying to do it in IMPORT tab why don't you set the imported DATE field in the SOURCE CODE of function module. There it will recognise sy-datum and you can very well write.

date = sy-datum - 3.

Hi,

You can check for the field, if its is blank then assign the default date in source code before processing.

Thanks

Thanks for your answers.

I'm not sure it answers my question : i want the default value to be visible when i test it (i'm going to use this fm with a web service from another app so the fact that the default value is visible is important so it can be changed if not corresmonding to the user needs) and if i just affect a value in my source code, it changes the value of the parameter but this is not visible at selection screen

Hello,

Did you try calculating the value of your parameter before calling the FM (ie date - 3 if the value is empty) and displaying it directly before the call so the user can still change it?

Hello Walter,

i'm not sure i can do this because i'm going to create a web service with this function module so if i set my value in a program before i assume it won't be set (and as far as i know, i can't generate a webservice from a program but only from a FM...).

Anyway, i'm going to try your way, thanks a lot
