Your post is very unclear - could you try re-phrasing, and/or simplifying? What is your use case / what are your step-by-step expectations / what issue(s) are you experiencing with each of those steps when you try?
I don't know why my process model always report the data to be saved can't be null, not sure which part I missed which been stagnate me for a month.
Do you think it is a good idea to start just another thread about the same issue we already talk about in at least two other threads?
It's ok,I already give up on it
it was not about that you should give up. Its about that we shouldn't have the same discussion three times of the same author. :) we can support you well, if there is "only" one thread.
then please tell me why there always null value for the data input?
did you check if your sail form is delivering the variables to the process? What is the process history telling you regarding variable updates?
tell me what is sail form? sorry English is not my first language though i went college in the USA,
It didn't report any variables in the process, just said you can't input any null value some etc similarly.
