P.R Associated issue

Question

Dear Experts
I have met a very strange issue about SD module.
First I created a sales order [ spare parts], only one item, material was A;
then our sap system created a purchase requisition, following the standard steps, our warehouse had this materials A.
Secondly, for the customers reason, our sales colleague created a new item of material A in the same sales order. as normally, we just need to change the price of material A.
Now, actually, we don't need to pick out sales order item 1 and delivery item 1; i use Movement Type " 413+E" to change the sales orders stock from sales order item 1 to sales order item 2;  i also finish the picking list of sales order item 2; but now, our system still create purchase requisition of  material A;  the new purchase requisition exception status is "07", but this new P.R still associate with sales order item 2.
Currently, i want to delete this new P.R, if  i do this step, I get a error message: <b>this item can only be deleted via the associated sales document.</b> could anybody give me a recommendation how to delete this new purchase requisition?
Many thanks for your kindly help!
Best regards!
Charles.

However, since PSIGN = * and * can be substituted for any value, PSIGN and E can also be interpreted as I. This can also lead to an undefined situation. In earlier releases, the authorization was denied on the basis of the rule E is stronger than I. This meant that superusers with assigned personnel numbers were not able to access their own personnel number. The programs have since been changed and now * is interpreted as I and is stronger than E. In other words, * is stronger than E and E is stronger than I, whereby * is interpreted as I.
this means that any P_PERNR object with PSIGN  value * will overrule any other P_PERNR object with PSIGN = E.
with this in mind, the new role would overrule all values from the old role.
