Specification of a key that is not relevant in the calculation will go unnoticed. Similarly, if you misspell a key such that it is not recognized, the incorrectly labeled input data will be ignored and the program will proceed as if the intended key had not occurred. This results in the application of pre-defined default values or in an error abort, depending on the case. Therefore, whenever the output suggest that part of your input has been ignored, check the spelling.
In this context we stress again: be alert on TAB characters: don't use them at all.
ADF may recognize a key if it is spelled incompletely, that is, if only some initial substring is given, and also if redundant characters are typed after the end of the key. The reason is that often only a small initial part of the true keyname is checked against the input items. Don't rely on this, however: it is not formally supported and it may get disabled in a next release without further notice.
We advise therefore to stick to the correct key names. In particular, you must avoid to use different abbreviated or elongated forms when a key occurs more than once in input: adf will likely assume that you want to indicate distinct keys and it will associate only one of them with the key you had in mind.
