Hi Fabian,
SAPbobsCOM.PickLists oPickList = SBO_Company.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oPickLists);
oPickList.Lines.BaseObjectType = "17";
oPickList.Lines.OrderEntry = 378;
oPickList.Lines.OrderRowID = 0;
oPickList.Lines.ReleasedQuantity = 5;
if (oPickList.Add() != 0)
    System.Windows.Forms.MessageBox.Show("Error : " + SBO_Company.GetLastErrorDescription());
//Screenshot 1
if (oPickList.GetByKey(Convert.ToInt32(SBO_Company.GetNewObjectKey())))
    oPickList.Lines.BinAllocations.BinAbsEntry = 1; // 05-SYSTEM-BIN-LOCATION
    oPickList.Lines.BinAllocations.Quantity = oPickList.Lines.ReleasedQuantity;
    if (oPickList.UpdateReleasedAllocation() != 0)
        System.Windows.Forms.MessageBox.Show("Error : " + SBO_Company.GetLastErrorDescription());
