UPDATE 21/07/2012: because of some requests the program is now improved: it uploads Excel instead of processing hardcoded data, it converts texts from the input to the length that i suitable for PO03 transaction and also writes proficiencies for qualifications evaluated in the input.
I was asked to build a program that would upload HR-PD Job object (“C”) definitions from. I would like to share the experience as well as the example coding. I am not going to pretend the example coding will save an experienced developer more than twenty minutes, but in my experience it`s always better to start with something than from scratch, right?
Last time I blogged about development for HR-PD Qualifications and the coding made the blog more useful than just talking I hope. If interested, check the blog here: All you need to know about HR-PD Qualifications from the development perspective.
As I understood my task, it had multiple parts. Unfortunately only one fraction can be generalized and reused. That is the upload part when you have data in a suitable format and call the function modules to put them to the database.
Let me elaborate on the application parts first (you don`t need to stick to it, it`s just that the experience at the end helped me understand how I had better started):
- First one needs to read the data from the data source (whatever the source is, can be an Excel file, XML file, web service – depends on your task). In most cases this part will be easy with the help from CL_GUI_FRONTEND_SERVICES class.
- Once we have the data in the system, it`s time to translate them into a suitable upload format. My task was to use very VERY strange XML file as a data source. Then this part becomes really challenging. I have good news too – this is the most difficult part of the task in my opinion. Lesson learnt: split the “data transformation” part from the “data upload” part carefully. If you start creating or linking objects as you go through the input file, your coding becomes spaghetti very quickly (hint: I learnt the hard wayJ).
- Last step is to upload the data. We all have the “same” SAP system with same function modules so my example coding should cover a great deal of basic scenarios, I believe.
What`s not covered by the example coding but is typically needed
My coding does not create the qualifications. I assume you already have the qualifications in the system. But what if the task is to create job descriptions with qualifications that are specific to the jobs (well, the power of the qualifications is to have a qualification created once and assigned many… so you`d better do it only if there is a catalog of qualifications used by job descriptions, that you`re uploading, and you want to create the qualification before the first use, so you don`t create more than you need)? Then you might want to reuse some of the coding from the previous blog.
- When you create the qualifications together with the job descriptions, you may want to put the external qualification ID to the qualification “short” field. Then you don`t need a mapping table between the “old” IDs and the “new” ones.
- When you create qualifications with the jobs, you typically group them (qualification groups) and for those groups you use one scale. But the interpretation of proficiency for one qualification often differs from the interpretation for other qualifications. You can define qualification specific proficiency interpretations (text descriptions). Check the qualifications blog for more info.
I wanted to use some custom text sub-types (of infotype 1002) to accommodate various text descriptions of my jobs. So I needed to create the sub-types first. That you can do/ define sub-type in table T778U and then define the time constraint in view V_T777ZIT.
While building your own program for the task, you will create plenty of text jobs I believe. Then you might wonder how to get rid of the test data. Then you might find the SE38 program called RHRHDL00 handy (ok, I am a developer, so for normal mortals there is a transaction called RE_RHRHDL00).
Last but not least: you want to see your jobs. I assume you know how to display them, but if not, try transaction PO03. Hope that helps.
