Increase number of line items in Purchase Order

If you experienced a Purchase Order getting cancelled because the message said it was too long.

In situation where you need to create a Purchase Order of at least 200 lines, you need to discuss with your Basis team to look at SM12 and verify the enque/table_size parameter and increase this value in order to permit more records in lock situation when you are creating your Purchase Order.
