Check for entry existence in Decision table

[Former Member]

Hi,

How to check whether entry is present in decision table or not in rule script?

Say I have only condition as A (Type string) and one action as B(Type boolean). Now if i want to check whether an entry exist in DT by using Evaluate Decision table by filling value of 'A', then value of 'B' would be false if either A is found in table with B value as 'false' or A is not at all found in table. How can i distinguish these two?

Regards,

Dhana

Hi Dhana,

I am not clear on your request. If i understand it correctly, your rules are something like this - If DT does not contain a particular condition value of A, then B is false. Else B is true. Am I right?

Or are you asking if the condition types and action types used in a DT can be retrieved and compared at run time during rule evaluation? i.e to check whether or not A is used in the DT as a condition value?

If it is the first case - you can make use of the special character (*) asterix which indicates "any value" to do this comparison. For the second case mentioned above, retreival of such information at run time is not possible.

Best Regards,

Arti

Hi Arti,

Thanks for reply.

Yes I need something like first case only. I tried using special character ( * ) . But decision table is not returning any record in this case. Will this special character work? I didnt see any documentation about passing special character for DT evaluation.

Hi Dhana,

Yes, the special character works.

Check out this help document - http://help.sap.com/saphelp_nwce72/helpdata/en/60/9edb034ebc40fc80ebe57d4c8dc166/frameset.htm

Here, in the example the use of the special character can be observed.
