Question / Problem:
Unable to change Validity Period in SAP.
Answer / Solution:When trying to change the Validity Period for the factory calendar in SAP, the following error is received:
"Message FK444 - Please enter validity area between years <start> - <end>"
This issue occurs when validity period specified for the factory calendar exceeds that of the public holiday calendar.
To resolve this issue, specify a validity period for the factory calendar that is within the validity period of the public holiday calendar. To extend the holiday calendar date range, do the following:
In the transaction SCAL, select the applicable holiday calendar from the list, and then click Maintain.
In the new window, change the Validity Period and the Valid to dates to include the desired date, and then click Save.
