We have a chained script and when the first script is finished the login-dialogue appears again and the user Needs to 're-login'.
Studio ,Foundation, Evolve
If you want the runner to log on to SAP before each linked script runs, choose Use individual script settings in the main Settings box, and then uncheck the ALC box for each script. (ALC stands for auto logon credential.)
you select 'all from first script'
you select 'custom' with ALC set as 'Use first script settings'
If the above mentioned steps do not resolve the issue then follow the below steps.
Delete the excel and re add and then republish the first chaining script to the new excel, the problem can come from the publication of the old excel, it probably keeping the old parameters without updating the new one.
