Unknown type "zcalc_result"-CodePudding

I am trying to run a unity test on an abap code using Eclipse. I am learning from a video series on youtube from a channel called Abap101. Everything was going well until he uses a variable from the zcalc_result type. It seems to run well on the video, but my code displays the error message "ZCALC_RESULT TYPE IS UNKNOWN"

I was expecting to run a test activate the code, but I get the given messsage when a I try to activate it.

CodePudding user response：

It appears that zcalc_result is a custom data-type which still needs to be defined. It could be defined as a type within the program using the TYPES keyword, or as a global type in the data dictionary (transaction SE11). The name starting with the letter z hints at the latter, but it could just as well be the former.

When you are following a tutorial, then it is possible that the author already did that but you skipped that part, that the author is going to do that next, or that the author forgot to mention it.

Judging from context, the intended purpose of this type is to hold a currency value. So if you want to declare it yourself, you would do that as a packed number (type P) with a reasonable length and two decimals. For example with this line at the top of the program:

 TYPES: zcalc_result TYPE p LENGTH 10 DECIMALS 2.
