Use of COM_LIM or change topology

[Kannan]

Dear Amit
 
We wanted to change the commodity balance limit via a 'scenario' file.
As usual, commodities are defined in many Base/ Sub-Res files without LimType.
Can we use ‘COM_LIM’ to change the default LimTyp to FX?  COM_LIM is shown as an attribute in VDEA2, but when we apply, it is not imported.

Similarly, we want to change the CTSLvl (from annual to daynite or so)

Could you please give some tips or template.
Thanks
Kannan
 
PS:  we do not want to change the base file to compatible with another version of the model.

You need to use a table ~TFM_INS-txt in syssettings to specify COM_LIM and COM_TSL.
