SRM: How to avoid standard message

[matthias_kasig2]

Hi SRM Experts,

concerning SRM 7.0. I need to deactivate or avoid messages from SAP Standard in relation to customer messages, which we create in z-namespace. This concerns accounting messages - Example: When trying to add a second accounting line for a stock/reservation material, we create a z-message saying: "No multiple Accounting possible". Still, when trying to add a new accounting line to a shopping cart position, other standard messages pop up, too, which is annoying. We fire our z-messages from BADI CL_BBP_DOC_CHECK_BADI. The point is: I have no idea about the message classes of the standard messages. Migh be the case they come from the ERP Backend. Still there should be a way to stop them, depending on other messages fom our doc_check Badi...

kind regards, Matthias
