We've got method to convert internal value to float, now it's time for next one which I didn't suppose it would be needed but when I was calling CTMS_DDB_SET_VALUE_ONLINE to show input screen with previously filled data by CTMS_DDB_SET_VALUE_INTERNAL then for multiple value characteristic I was always receiving one additional line to these which was passed by me in export parameters. The funny thing was that it wasn't the case when CTMS_DDB_SET_VAL_FROM_OBJECT was used. Of course this line was initial but the values were treated after as imputed by user. So as always I started to debug the code to see why it's happening. Finally I found that internal table WS in the function group CTMS was not refreshed during the call of CTMS_DDB_SET_VALUE_INTERNAL.
As I couldn't refresh it in any call of FM from this function group I had to use old trick with assignment of data from program in memory. But firstly I check with FM CTMS_DDB_HAS_VALUES_INTERNAL if any values are already there.
IT_API_CHARTYPE TT_API_CHAR ->Table type for structure api_char_tab
Welcome back :-)
Some time ago I presented how I get data from classifications to reference data variable ( or table). If you feel comfortable with my method then we can go further. I had a task to update some characteristic values from ALV grid, this would be not a problem at all if the characteristics would be defined from the begriming, but they weren't. In that case I couldn't just add needed fields to fieldcatalog and call FM to update characteristics when save button was pressed. I realized I need dynamic structure for ALV which will call standard screen for characteristic update. If this could be done then I could omit carrying about type of characteristics (date, number, char ) and if it is single o multiple type. So I started to dig in SAP, debug standard functions and I was finally able to prepare all needed functions.
So firstly what was needed (additionally to previously presented methods):
In this and following parts of this tutorial you'll see all mentioned methods and example of their usage. You can also find the code in attached NUGG file for easier import to your system.

Some years ago I was asked to create a report to check if in our Z-developments we are using authorization check or not. Of course not in all developments you need to have authorization check as sometimes standard SAP function modules provides proper checks inside them, but in many cases developer should take care about them inside the coding. The code I will provide below will scan program for AUTHORITY-CHECK statement and will collect the parameters of the call of AUTHORITY-CHECK. But one thing you have to have in mind, if developer used separate FM or class to check authorization then this report will not show any authorizations for program as it's looking only in the code of the program and not for the authorization-check inside called FM or classes.
Please look through the code or import to your system using nugg file.
When you create a report or transaction that handles a lot of data with multiple selects and functions that are doing some manipulation of the data, or you have to call in this report a function module thousand times and you want to be sure that no matter how long it takes it should be done but your system administrators have put some restrictions for time limit then you have to use one of this methods:
Call commit work whenever you want to reset the counter of running time for your transaction (especially if you haven't done any update into database tables)
If commit work doesn't work or you don't want to use it at the moment then you could use FM TH_REDISPATCH with the check_runtime parameter equal to 0.
You could also you FM SAPGUI_PROGRESS_INDICATOR for the same purpose but keep in mind that showing indicator too often can slower your program.
Both of the methods will make that the counter for application runtime will be reset, but be careful this can make you application run really long. Also if you got one select statement which takes more than maximum runtime for your system then it will not help so you have to prepare your coding to be able to use any of this method, like spliting the selects statements to parts or to select single in the loop.
Although it's nice to know this possibility my advice is to not to use it very often as the less time you have for program run the more optimized code you can provide, so it's really something that you use if you do not have other choice and you agreed that with your system admins.
Examples: (run the program and look into SM50 to see the runtime)
You may noticed that standard transaction MD07 and MS07 offers basic filters on selection-screen which allows user to select materials they are responsible for, the problem comes when in your company users wants to be more precise in filtering or when the responsibility is set not only on a base of MRP controller. Fortunately SAP gives us the possibility to call MD07 and MS07 with our own list of materials using dummy transaction codes MDC7 and MSC7. All you need to do is to prepare a table of type MDMWX, export it to memory 'START_MD07' and call dummy t-code. Bellow you can find an example of the report to call MD07/MS07 with own material list where on selection screen you can find for example purchasing group which is not available in standard. You can also find a link to nugg file.
Today, as a first entry in Beginners part I'd like you to show how to build parameters on selection screen. All this information you can find under F1 help but here you've got visualization of what's written there. Hope it will help to understand this statement. As embed video is my first one then please accept my apologies in case of errors and wrong pronunciations as English is not my native language.
During creation of selection screen or normal screen for your program you declare some fields and you want to use with them standard search help but with some modification like putting values to one of the search help parameters or making the SHLP parameter readonly then structure DDSHIFACE and FM F4IF_START_VALUE_REQUEST comes with a help. DDSHIFACE as you can see do not has much fields and for us the most interesting will be SHLPFIELD, VALFIELD, VALUE and DISPFIELD. In SHLPFIELD we will store the name of the SHLP parameter (names you can check in SE11), VALFIELD if filled will tell FM that value of this SHLP parameter should be returned to the user (value isn't important in our case so i'll put 'X' ). VALUE if filled set the value of SHLP parameter before showing the results of F4 call so we can directly restrict searched range with some data. Finally DISPFIELD if set makes the parameter on SHLP display only .
If you have to adjust conditions for your purchase order line and if during the use of method if_purchase_order_item_mm~set_conditions in BADI ME_PROCESS_PO_CUST you receive an error MEPO151 "Data from Business Add-In ME_PROCESS_PO_CUST not adopted" then after you check SAP notes for that error and none of them help then you may try with solution which you can find bellow. The endless loop appears because set_conditions method force re-check of the item. To avoid running set_conditions more than once in one check of the item I used abap memory to store data about each line that was check. I've created simple structure with ebelp and "set" fields on a base which I know if I had to run setting of conditions or not. Maybe it's not the nicest solution but it works quite well :)
The form which you can find bellow you have to run at the end of processing of method process_item of ME_PROCESS_PO_CUST to be sure that other form will not force SAP to re-check the item again.
When you will want to create a customization table for your program but you want to do it that way that you want to have many key fields and some of them can be empty which would mean that this is valid for all entries then you have to do some little coding to handle it as you just cannot check only if key fields are same as in your checked structure. There is a way to do it and the method described can be used in all programing languages. I will show you two ways - static and dynamic.
In static one I will hard code key field names in the code which makes that you have to rewrite the code each time you change the structure of your configuration table.
Dynamic way when done once then doesn't have to be redesign as I will use cl_abap_elemdescr and cl_abap_structdescr to get key fields.
Ok, firstly we need to create our configuration table in dictionary using SE11. As sample I will create table only with two key fields on a base whom I will check the configuration.
