Purchase orders, Scheduling agreements, Contracts and any other MM document may present a considerable history that includes different types of subsequent documents: goods receipt, invoice receipt, service entry sheets, down payment documents, delivery cost documents, etc.
Purchase order history documents are saved in 2 main tables: EKBE and EKBZ. If these tables present a considerable number of entries, each time User access MIRO transaction and enter a document as reference, system will need to search in all the historic documents and this will seriously affect performance.
To check how many entries are in EKBE and EKBZ tables, follow these steps:
Go to SE17 transaction > enter the table name > fill EBELN with the document number > Execute
It is necessary to aggregate Purchase order history using ME87 transaction (RM06EKBE report).
