You have created a custom Purchase Order type. You are using this customer PO type and as outlined in KBA 2741056, you have configured one or more text type to be issued on your purchase order output form.
When you make a change to one or more of these texts you expect a new change message to be triggered and the new form
to reflect the changed text, but no output is issued. (This issue only affects custom PO types)

Reproducing the Issue
1) Create a Purchase order for a custom PO type adding an item text (F01)
2) Save the PO and check the output type generated
3) The item text (F01) is included in the PO form
4) Change the item text (F01)
5) Save the PO
6) No change message has been generated
Incomplete customising. When copying the NB PO type the table entry that enables change messages for text changes is missing.
This is currently a gap which will be resolved for release CE2111.
Change messages will only be triggered for text changes, where the standard PO type NB is used in the meantime.
