How to define Expression in action condition definition?

[Former Member]

Hello all,

I have a question about expression definition for action.

I want to take yesterday's date from system. But there is no available Container Element.

So i want to use system field %DATLO%(system currect date = today's date) to decrease one day. For example: %DATLO% - 1.

But it is error, i don't know how to express.

If need to creat a new element, how to evaluate the new element?

Thank you very much.

Hi Xi Ming,

I had a similar requirement. You can do this by creating a new container element/parameter. Select Object Type and choose CL ABAP Class. Create a new class (SE24) and implement interface IF_BUSINESS_OBJECT_PPF. This makes sure that your class is available for selection. Create in this class a new method (i.e. YESTERDAY) with a returning parameter (i.e. RESULT). Make sure it is a type that is compatible with the field you want to compare it to. Within in this method you can make a line like 'result = sy-datlo - 1.'

It probably isn't current for you but it may help people experiencing a similar issue.

With kind regards,

I would say to follow the following path.

Create two container elements.

1. ZZYESTERDAY with type SYST-DATUM

2. ZZ1DAY with type CHECKNUM and Initial Value = 1

Now create one Container Operation in your workflow before the condition where you want to check.

Give some STEP Name.

Result Element = ZZYESTERDAY

Assignment = =

Expression = %DATUM%

Oprator = Subtract ( - - )

Expression = ZZ1DAY

Now when workflow runs you will gate the date value of yesterday in ZZYESTERDAY Container element which you can use in your workflow.

No. the issue remain to exist.

Maybe, only can enhance container parameter.
