Subject: Importing New Branches into WEAP from Excel Posted: 4/28/2016 Viewed: 5264 times
I am developing a water management model of certain African countries in WEAP. I had to make a 'Key Assumption' to represent 1000 small districts and their population. I was wondering if I could have it in Excel and directly import them into WEAP. But i did some digging on the user Manuals and it had the following words
"WEAP can only import data that corresponds to an existing branch/variable/scenario"
So i believe that I need to create these 1000 branches in WEAP and then I can use the import/export function to deal with the EXPRESSIONS.
Can someone guide me if my understanding is right and if wrong, how do i take numerous amount of branches into WEAP without clicking and adding them one by one.

You can use the WEAP Application Programming Interface (API) to automate the adding of branches. See the WEAP help topic for more information: Advanced Topics \ Automating WEAP (API).
Here's the Visual Basic Script (VBS) code you use to create 1000 branches, named with sequential numbers:
Set ParentBranch=WEAP.Branch("\Key Assumptions")
For i = 1 to 1000
Set NewBranch = ParentBranch.AddChild("Branch " & i)
If you have the names of the new branches in an Excel spreadsheet, you could use Excel's Visual Basic for Applications (VBA) language to write a simple macro that would create branches using names from Excel cells. For more information on controlling WEAP from Excel, see the Help topic: Advanced Topics \ Automating WEAP (API) \ Exploring the API.
