I just verified, and it works as expected. I am able to pass the parameter to DataTransform B from DataTransform A, though it was in different branches.
Could you please ensure the parameter page is passed to Data Transform B(attached screenshot for your reference)?
Data transform B in branch BB is a NEW created rule that not exist in any ruleset before, so it’s not checked out from existing rules, it’s a new rule.
Could you try like this?
BTW, i do not select the pass param page check box as it’s not a necessary for passing param.
I just put a value in param field, which works fine in same branch.
I created Data transform B in branch BB as a new rule, which works as expected. I was able to pass the parameter, and I was able to confirm in the tracer.
ok, seems you did not reproduce the problem. Is your calling data transform is in another branch than B and also a new rule (seems I missing to mention this point) ?
If so, then let it be, anyway it just impact testing. I can by pass by copy all DT to one branch to test.
