I've a problem with an add-on installed in a customer. This add-on creates a button item when a sap's form is loaded. If I execute this add-on with a user (A) sometimes shows the message "Error '-70001 (ffffe4a7)' en tiempo de ejecución Item-Invalid Item", but if I reload the add-on it executes property. Furthermore, this add-on with other user (B) executes property.
Can help me anybody? Thanks.
