Hi,
Open the Chain in Planning mode ( RSPC or RSPC1) >> Right click on the Start Process >> Display variant >> Change Selections >> Click on Date/Time tab >> there click on Periodic Values Tab
There Click on Other Period >> there in the Day(S) field enter 6.....
Then Check and Save >> Again Check and Save .........
Then in the Scheduled start field give the date when the Chain is going to run for the first time.............and Enter the time in the Time field....
Then the Process chain will run on 6th of every Month...
And if there is holiday on 6th working day then it should execute on next month.So there is restrictions near by periodic values . There you maintain factory calender id and check "Do not execute job on sunday or holidays" check and transfer.
Thanks,
