On a few windows in SAP you can find item uid's like:1470000032-1470000007
Where they have added a dash to the item uid. If you try to use this in the dynamic syntax in B1UP you will get an error.
This is unfortunately not something we support as it was a mistake by SAP that they created items with this type of UID.
SAP only did it on a few windows and our dynamic syntax engine cannot handle this special syntax.
We currently do not plan on supporting this as we have not found a good way of adding it without breaking backwards comparability.
