Reinstating a Deleted Master File Value 
You may decide that you want to reinstate a dimension value that you previously selected for deletion. You can reinstate the value using the Deletion mark function on the Delete Master Data: Basic Screen.
To reinstate a master file value from the Delete Master Data: Initial Screen:
– Table name for the dimension information that you want to reinstate.
– Database field name to which the master data refers.
– First master file value that you want to reinstate.
– Last value of the range of values that you want to reinstate.
A dialog box appears.
If the master file values are for all companies, leave this field blank.
The Delete Master Data: Basic Screen appears.
The master file value is again valid.
