How Entity Locking Works in Actual Data Templates

In the example below, two Companies in the Actual Data Template have different locked periods. The Company in first row is locked until April 18 and the Company in second row is locked until May 18.

Data entry is not allowed for the Company in the first row until April 18 and data entry is not allowed for the Company in the second row until May 18. Cells highlighted in yellow allow user entry.
