Hi, often this happens because the data of your items is not complete or contains characters that don't work well with JSON. The first things I'd check: - Do all your items have the home and holding branch (952$a and $b) set to a correct value? - Do all your items have an itemtype set? (952$y) Hope that helps, Katrin On 14.01.20 05:48, Nur Ahammad wrote:
