The specified date interval overlaps the date interval of the formula version #### Tag with ##FG##

When I Approve or Activate the BOM I'm getting the below issue, then finally i got resolved it.

Go to the Particular line item and check the where-used. You can find a new BOM and check with the same Item is mapped with the another BOM ID.

You will find the same item is mapped with the another BOM. Just remove the same item in the existing or another BOM. Add the new Item in that same BOM.

Now you can Approve or Activate the BOM with out the error.

Be Happy....!
