Help Restriction Purchase Order Transaction Notification

Question

Good afternoon experts community'm doing a lock which I doubt as raise it, the case is as follows:
The purchase order should not be created if the unit price of the item is higher than the price of the price list of sap, the problem is that now they will start to use the extra coin price list, that is why it is requires blocking the creation of the purchase order if the order price is higher or not applicable to the two alternatives we have in our price list.
In advance I will be grateful if anyone reads this post and I can reach out to fill this requirement and also bring something more to my knowledge.
best regards!
example
if @transaction_type = 'A' and @object_type='22'
begin
    set @itemcode =(select top(1) o1.itemcode
                      from opor o inner join por1 o1 on o1.docEntry = o.docEntry
                                  inner join ocrd c  on c.cardcode  = o.cardcode
                     where u_facnum is not null
                       and  not exists(
                                       select *
                                         from itm1
                                        where itemcode  = o1.itemcode
                                          and pricelist = c.listnum
                                          and (price > o1.Price and AddPrice1 > o1.Price  or itemcode in ('FLETE','SEGURO'))
                       and  o.docEntry = @DocEntry)
   if (
       select count(*)
         from opor o inner join por1 o1 on o1.docEntry = o.docEntry
                     inner join ocrd c  on c.cardcode  = o.cardcode
        where u_facnum is not null
          and  not exists(
                          select *
                            from itm1
                           where itemcode  = o1.itemcode
                             and pricelist = c.listnum
                             and (price > o1.Price and AddPrice1 > o1.Price  or itemcode in ('FLETE','SEGURO'))
          and  o.docEntry = @DocEntry
       )>0
   begin
     set @error = 1
     set @error_message = 'Error el articulo '+@itemcode+' no concuerda a lista de precios del cliente.!'     
   end
  end

Hi,
Please avoid using Transaction Notification if you want to insert a B1 object via DI API using the integration framework.
The reason is, that the integration framework uses the DI API logic and this transaction notification runs on top after the DI API process is finished. Therefor it is not really part of the DI API process.
This could cause an unexpected exception in the DI Adapter of the Integration Framework.
My proposal is to check your mentioned logic within the integration framework instead of using the transaction notification at the end.
E.g. Build a flow using a SQL Call atom to retrieve the pricelist price you want to compare with.
You can built a conditional processing in your integration flow to avoid the creation of the purchase order or directly change the price on the flow.
Another option is to check your logic, create the purchase order with status "for approval" and inform the keyusers via B1 alert message out of your integration scenario step.
Best regards
Bastian
