IFS - IMF data with Stata plugin

Dear all,

I use the Stata command dbnomics to download data from the IFS-IMF database.
I identify the indicators available in the database using the Stata command: dbnomics datastructure , provider(IMF) dataset(IFS) clear
I have a problem downloading some specific indicators. For example, FDSAOP_XDC and FOSAOP_XDC are two indicators that are available in the database.
I have no problem downloading the first indicator:
dbnomics import, provider(IMF) dataset(IFS) sdmx(Q…FDSAOP_XDC) clear
I get “147 series found and loaded”
With the following code for the second indicator:
dbnomics import, provider(IMF) dataset(IFS) sdmx(Q…FOSAOP_XDC) clear
I get an error message: “server reported server error
r(675);”

Can anyone help me solve this?

Regards
Vincent
