To keep the history of the order original data, the table SCY - (Purchase Order History) is used. This table is always updated when some change in the order is made.

Whenever there is a change in the purchase order, a record of history is generated in the table SCY (Purchase Order History), which stores all previous data of the purchase order, saving an identification number for each version in the Maint. Version field.

When the purchase order is changed for the first time, this field is saved with the content 0001. When changed for the second time, this field is saved with 0002 and so on. The current order version is always stored in the table SC7 (Purchase Order). If the purchase order is not changed, there is no record of the order in the history table.

You can query the table SCY (Purchase Order History) through Generic Query.
