Hi Eric, Hi Edy,
Finaly, I decided to use the following solution :
SBO_Application.OpenForm(enSAPTableID.cin_DocumentDraft, "", SBO_Company.GetNewObjectKey)
muc_GoodsIssue = Me.muc_ParentAddOn.SBO_UserFormsCollection.Item(Me.SBO_Application.Forms.ActiveForm.UniqueID)
It's mabye not the good one but it's working! Thank you for your help.
Regards
