automate MSS substitution rule activation with 'Fill In'

Hi,

I have a question about the substitution, shipped with EhP7. There is the possibilty to add the rule as 'Fill In'.

If I add the rule, the substitute will get the information in his overview directly. This option does not look at a maintained absence in infotype 2001?

The reason for my question is the following:

I would like to automate the activation of the rule, when the system (or especially a report) does detect an absence in infotype 2001. Only if that is the case, the rule should be activated. The result of this procedure is, that the substitution rule only has to be added once initially (of course for one substitute).

I read different articles and the part of the HR600-course-material. With that and my testing in a system, I think that there is no such automation I described. Am I right?

Thanks in advance.

Best regards from Germany
