How to copy long text from production order to automatically created P.R

Question

Hello experts,
I want to add some text to the long text , in the production order and save it.
There is an external process in our routing, in which when the order is saved and released, there is a P.R created automatically.
My requirement :-  The text in the long text tab of the Production order should flow to one of the text types {Item text} in the P.R item created.
I checked in SPRO [ IMG-> MM->Purchasing -> P.R-Texts for PR-> define copying rules].
For text type ,  'Item text' already has  the text linkages : Order/network, with source texts "component text' and 'transaction text'.
However, the text being maintained in the order is not flowing on its own anywhere into the P.R created.
Is there any other config that needs to be done to achieve this?
Regards
P.R

Hi, A production order long text exists at a header level and a Purchase req gets triggered at an operation level of a production order during external processing.
  So if you expect a mapping of a header text to operation level text, it should not be definitely possible in the SAP standard. (May be an enhancement would still work but you need to decide on it).
If you maintain a long text at the same operation where you trigger a pur.req (a text on your own or via a standard text key-CA10 tcode), you would see that populated, at the item-level text tab of the generated pur req automatically, as a standard behaviour.
Hope you would go with the standard system behaviour.
