Update a decision table automatically

Hello experts,

Context : SAP PO 7.4 java only / NWDS

I create a decision table with rulesComposer in NWDS.

I have a BPM wich check the decision table and it works fine.

What I want to do is to udpate this decision table.

It is a decision table with two columns, if the value to test is in the first column the newValue (from the second column same line) associated is returned.

I want to add some value on the first column with default value associated (on the second column same line).

And I don't know how to do it.

Could you help me please ?

Thank you

I don't know if I respect the rules to start this discussion, if it's not I am sorry.
