If I define 12 different series for JE, one for each month (say 201401001, 201402001, etc.), then regardless in which posting period I create an A/R invoice, the automatic JE will always use the “Default” series and not the series with the same PI assigned to the posting period.
But this seems strange. Do I need to change the default every month? and if I do, and I need to post last month invoice, I need to go back and change the default again??
SAP Note Number: 1013455 mentions that
You create a Journal Entry, whether manually, or automatically from a document. There is no validation that the period indicator of the series correspond with the period indicator of the current period.
This behavior is a system definition. It was set intentionally to enable users to work with one series for journal entry, even if the company is working with period indicators.
