multiple parameters from XLSX to GDX - ERROR 492 - symbol not in GDX

[Archiver]

Hit there,

I have the following code sequence:


1) This is a textfile I stored as "input.txt"

$onecho > taskin.txt
dset=t rng=import!a2:a35041 rdim=1
par=xDA rng=import!b2:b35041 rdim=1
par=cBApos rng=import!G2:G35041 rdim=1

$offecho


2) This is the GAMS Code which is supposed to create a GDX File for the parameters cBApos and xDA:

$call gdxxrw.exe INPUT_DETERMENISTIC.xlsx @input.txt

$GDXIN Test1.gdx

set t /1*35042/ ;

$load t

display t;

parameters
cBApos(t) costs for gas and CO2 positive xval
xDA(t) sold amount in the day ahead market (MWh)


$load cBApos xDA

$GDXIN




I receive the Error CODE 492 - Symbol not in GDX

Can someone help out? Do I need first to define something in the GDX file?

Stefan,

The call to gdxxrw generates INPUT_DETERMENISTIC.gdx not Test1.gdx
