After hours and hours i give up and hope to find the solution with you guys.
I created an UDT -> defined some UDF in this table and then registered the whole thing as a master data to an UDO.
now i am trying to make some rules on this Object using Coresuite Optimizer which uses almost same syntax like SDK!
By trying to get specific Fields from this Object using this code for example
TextEdit.GetFromUID(pVal.Form, "22_U_Cb").Visible = false;
where my Item ID is 22_U_Cb as i can see the system gives me an error Message because the Item cant be found.
is there any specific way to get my Items in case of UD Objects and fields?
when i use the same code to any System Object everything works fine.
Any suggestions or experiences about that?
