Post to Job or Crop Cost

	If checked, all non-inventory line items additions or changes for this P/O
	will be distributed to a requested Job/Crop number and cost code. 

	This flag, whether checked or not, may not be changed once there are
	line items on the P/O. 

	If items have already been added to the P/O that should have been distributed
	to a cost center, either use the Job/Crop cost 'enter transactions' to get 
	them distributed OR delete all the items from this P/O, check this flag, then
	re-enter the line items.
