Hello Everyone,
let me briefly give you some background infos, before explaining my issue:
SAS offers the "VARINITCHK" option, which "specifies whether a DATA step stops or continues executing when a variable is not initialized and the type of message to write to the SAS log".
Now, I am using this option in its strictest version, id est: a DATA step stops executing and writes an error message to the SAS log when a variable is not initialized.
Now my issue:
My chosen strictness level of the aforementiond option causes the cancelation of batch scheduled, (automcatically) written Data Integration Studio Jobs, since it turns out, that in some occasions the autogenerated code is not "clean". Sidenote: at least I can uphold my quality standard, since the "quality guarantee" I wanted by having only "clean" code to be run is fulfilled 🙂
BUT: how can I correct the "pollution process" of DIS? Meaning: is there a possibility to modify the etls-macros, which are being used during the code generation process of DIS?
Where exactly are the etls-Macros located in the filesystem? (I guess the name of the macros is derived from the good old days, when DIS was called "ETL Studio"). As far as I know they are "hidden" in some ominous Java classes.
For example, using the SCD2 Table loader transformation, is problematic, since it uses the "ETLS_SCDLOADER" macro to autogenerate the job code which is "polluted" since sometimes the line
call missing(of _all_);
is missing when declaring variable attributes within a data step.
