I have a business requirement to add a new custom field, at item level, in the Purchase Order transaction (ME21N/ME22N/ME23N). It is a char10 field.
I have already created this new field, which is correctly updating the EKPO table.
But now the business want to update this field for all Purchase Orders created in the past. I think that I will be able to update it by using a BAPI, however what I really want to know is if there is any problem in doing this since some POs were created more than 3 years ago and for which there are goods and invoice receipts.
Will this create any inconsistency in the subsequent documents (Goods receipts, invoices) generated after the PO was created?
Thanks for the help.
