I am trying to post SALES order data from Proxy using PI system, for testing the scenario, I went to the proxy and from the menu, selected test then I upload the XML content coming from SAP PI system, the moment I click on execute the system prompts me with an Information Message -No Vendor specified, As I thought it was just information message I tried to continue, then system took me to XML editor, where with peroming any changes, I tried to execute the proxy the same message pops up, can any you help me with this regard.
I have checked mutliple forums and I have found out the following.
There is no fix yet for this 'No Vendor Specified'.
When we posted a message to SAP (OSS), they told us to change the message at class 00 / number 001 to &1&2&3&4&5&6&7&8
If so how to implement the above stated how should I change the message class.
