ALL VERSIONS

• Batch export did not work with some foreign languages - fixed.

ADVANCED VERSION

• If there is a scenario map table in reports, the “Scen” column will appear in the Results view.

2.017.1.1 [10Aug23]

ALL VERSIONS

• Export capacity from pivot table to xlsx is increased to 1.048 million rows.

2.016.1.1 [25Jul23]

ALL VERSIONS

• Handling links in Excel files: Files with remote links were freezing the application during Sync process in some cases. Excel objects are now opened with the following settings:

  • Application.AskToUpdateLinks = False

  • Application.DisplayAlerts = False

  • getWorkbook=Workbooks.Open(bkPath,updatelinks:=0,readonly:=false)

• CmdF_Top attribute introduced to inject code before the GAMS call in VTRUN.CMD file.

2.015.1.1 [14Jul23]

ALL VERSIONS

• GAMS Engine: Users can specify namespace and model under GAMS Engine settings (Case Manager). This will enable users to use thier own GAMS Engine account to launch runs in the cloud.

• Attribute master: Interpolation option indication (green color) has been removed. Complete information on default I/E option is available in the table at the bottom of that form.

• Case Manager: Select all option for saved cases.

• Pop-ups will appear on the same screen as the application (when using multiple screens).

2.014.1.1 [08Jul23]

ALL VERSIONS

• VA update: Process/commodity lists are shown on VA - as per the process/commodity filters.

• Variables $case_name and $vd_file_name introduced in the VTRUN.CMD file, which can help automatic post-processing routines.

• Display issues with 4k monitors and higher zoom levels have been fixed.

• DD writing has been revamped. There is no change in the output but large models will see significant performance improvement.

• Veda2.0 has two very powerful features for managing sets - Sets Browser and Sets Editor. They have been moved from the Tools section to a new module - Sets, hoping that visibility will make more users take advantage of this feature.

2.011.1.1 [27May23]

ALL VERSIONS

• [Debug] update excel was writing only two decimals.

• Veda Assistant: Create Tag button on Information - Veda and TIMES parameters screen. We will call this VA

2.010.1.7 [07May23]

ALL VERSIONS

• [Debug] Default PCG allocation was wrong for some processes if parameter declarations triggered the creation of a single-commodity CG. Here is the streamlined logic:

  • PCG declaration via the primary_cg col of ~FI_Process has the second priority.

  • Veda default PCG will be used only if no declarations are found from the above sources.

  • If a parameter declaration triggers the creation of a single-member CG, which is also the commodity that Veda has identified as the default primary commodity, then the CG will be used (instead of the commodity) as PCG - ONLY FOR DMD processes.
