Conversion routines on SAP 4.0B

Hi All!
I have a piece of software running on SAP 4.5 and I have to port it to SAP 4.0B (The horror !!!). I managed to solve all the problems but one. In version 4.5, author created many domains with conversion exits and some of these conversion exits are missing (especially - timestamp conversions) on 4.0B (e.g. TSTPS). This may sound like noob question but is there any way to add missing conversion exits to 4.0B or write new, custom ones? I haven't done it before and I don't even know how to start.
I will appreciate all the help you can give me.
Thanks in advance
Tomasz

Hello Tomasz,
Poor guy! Working with 4.0B on April 1st is an appropriate day for sure. A year ago I was working on 4.0B -fortunately for a very short time. This was not so much a problem because I am working with SAP since the lowest version. Nevertheless it was a pain! First: I don't know a 100% solution and I am not able to login into this guy anyway.
To solve your task you have to create your own conversion. TSTPS is linked to a simple ABAP program. Under 4.0B you have to create this program. As far as I remember those conversions are screen/ta related. Go to the field where the conversion has to accour, click F1 and then go to technical settings. There should appear a box which is responsible for the conversion routine. From there try to proceed.
Sorry, I can not provide you with more (because I don't know).
May be it helps when you login to SAP Help Portal (on the web).
I wish you the best,
Heinz

What is use of Conversion Routine in Abap dictionary

Hi,
Can any body please tell me the proper use of Conversion Routine in Abap dictionary.
Please give me a practical example where it has been used.
Thanks
prabhudutta

hi,
here is help for conversion routine
Conversion takes place when converting the contents of a screen field from display format to SAP-internal format and vice versa and when outputting with the ABAP statement WRITE, depending on the data type of the field.
If standard conversion is not suitable, it can be overridden by specifying a conversion routine in the underlying domain.
A conversion routine is identified by its five-place name and is stored as a group of two function modules. The function modules have a fixed naming convention. The following function modules are assigned to conversion routine xxxxx:
CONVERSION_EXIT_xxxxx_INPUT
CONVERSION_EXIT_xxxxx_OUTPUT
The INPUT module performs the conversion from display format to internal format. The OUTPUT module performs the conversion from internal format to display format.
If a screen field refers to a domain with a conversion routine, this conversion routine is executed automatically each time an entry is made in this screen field or when values are displayed with this screen field.

Raghavendra

How to remove conversion routine "ABPSN"

Dear gurus,
In my transfer rules, under the tab "DataSource/Trans. Structure", I have a field PSPID whose "Conversion Routine" has the value "ABPSN". This conversion routine converts the external format to the SAP format which, however, is not what I want. I want to remain the original format so I need to remove this "ABPSN" conversion routine. When I double clicked it, it linked to the InfoObject 0PROJECT maintanace screen. On that screen, I removed the conversion routine "PROJ" for 0PROJECT, but still ABPSN remains and the data loaded into the InfoCube have been converted.
So how can I remove this ABPSN convertion routine?
Thanks in advance.
Jin Ming

Hi Jin Ming,
Conversion Exit ABSPN is related to WBS element and not project at R/3 side.
But at BW side this routine internally calls Project routine .
The Process is,
1. Delete all transactional data , from related ODS & Cube wherever 0PRoject is used .
2. Delete master data from 0Project.
3. Change object 0Project remove the conversion using Tcode RSD1.
4. Load master data for 0Project.
5. Load transaction data.
Hope that helps.

Mr Kapadia

How to "Custom conversion routine" in BW

Hi team,
The R3 table level field has converion routine which stores the value as "A" .
When you display this in application (or) using ALV, it shows as "AB". There are custom function modules behind this conversion routine.
In BW, when we extract until PSA, we are getting "A".
I see the option at Info object level to write" conversion routine" but how and where to start this conversion routine in BW.
In BW, we want to show "AB"
Thanks
Angelo

Hi,
this problem is solved in transformation PSA to InfoObject using formula or routine.

Regarding "TYPES & "CONVERSION ROUTINES"............

Hi abapers,
Can we have a code snippet as given below,
TYPES : NUMB TYPE I VALUE 100.
DATA : NUM1 TYPE NUMB.
WRITE : / NUMB, NUM1.
what will be the output?. Will the value 100 be copied to the field NUM1?
Next question is regarding "conversion routines". I read that "conversion routines" can be assigned to fields(variables) in abap?. What are "conversion routines"? What are their purpose? Also explain me the purpose of "EDIT MASK"?
Thanks in advance.

Hi,
Conversion Routine..
I will just give you an example.....
For us in user interface English language is EN... but for system it is Just 'E'...
There conversion will happen from user to system and while retrieving from system to user..
So there are two routines for that.
CONVERSION_EXIT_ <conversion routine name> _OUTPUT
CONVERSION_EXIT_ <conversion routine name> _INPUT.
These coversion routines do the conversion job
check this link..

What is conversion routine which is found in data element

Hi all,
I was just trying to creating a data element assigned to a particular domain in se11. While i am creating i can see a conversion routine
Can anyone tell me what is the use of that conversion routine with an example.
thanxs in advance
hari

Hi,
Depending on the data type of the field, there is a conversion when the contents of a screen field are converted from display format to SAP-internal format and vice versa. If this standard conversion is not suitable, it can be overridden by defining a conversion routine in the underlying domain.
Conversion routines are identified by a five-place name and are stored as a group of two function modules. The function modules have a fixed naming convention. The following function modules are assigned to conversion routine xxxxx:
CONVERSION_EXIT_xxxxx_INPUT
CONVERSION_EXIT_xxxxx_OUTPUT
The INPUT module converts from display format to internal format, and the OUTPUT module converts from internal format to display format.
When is a Conversion Routine Executed?
If a screen field refers to a domain with a conversion routine, this conversion routine is executed automatically when entries are saved in this screen field or when values are displayed in this screen field. The conversion routine of the domain is also triggered when the field contents are output with the WRITE statement.
Table SPFLI in the flight model contains information about the flights offered by the carriers. The time for each flight is recorded in field FLTIME. Enter and display the time of the flight in input templates in the form HHH:MM (hours:minutes). Store the flight time entered in the database as an integer number (number of minutes of the flight). An entry 3:27 is therefore stored in the database as 207 (3 hours, 27 minutes = 207 minutes).
Field FLTIME refers to domain S_DURA, to which conversion routine SDURA is assigned. The value is thus converted by the two function modules CONVERSION_EXIT_SDURA_INPUT and CONVERSION_EXIT_SDURA_OUTPUT.
A conversion routine can also be triggered by specifying its five-place name in the attributes of a field in the Screen Painter or with the addition USING EDIT MASK <Name of conversion routine> in the WRITE command in the program. With the USING NO EDIT MASK addition in the WRITE statement, you can skip a conversion routine defined for a domain when outputting.
Parameters
The two function modules of a conversion routine must have precisely two parameters with the names INPUT and OUTPUT for the value to be converted and the converted value.
The INPUT parameter in the INPUT conversion and the OUTPUT parameter in the OUTPUT conversion should not have any reference fields because the value passed in the call could have a different length than that expected.
Programming Conversion Routines
ABAP statements that result in an interruption of processing (such as CALL SCREEN, CALL DIALOG, CALL TRANSACTION, SUBMIT, COMMIT WORK, ROLLBACK WORK, MESSAGE I, MESSAGE W) are not allowed in conversion routines.
Only A messages are meaningful in output conversion, but A, E and S messages can be triggered in input conversion (although S messages are not very meaningful here). E messages result in an error dialog. Exceptions are not intercepted in the call.
The output conversion is also triggered with WRITE and WRITE TO. The conversion routine may therefore occur very frequently with lists. The output conversion should therefore be programmed as efficiently as possible.
No external performs should be used in conversion routines. Programs that are called externally use the table work areas of the first calling main program. In conversion routines this can result in errors that cannot be easily analyzed since they are sometimes called at unpredictable times in the program flow.
Pls refer link which contains code as an example to conversion routine used in abap.

Month conversion routine

Hi All,
I have a field applied month in an ODS and the ODS is being updated by a Flat file. The format of applied month is YYYYMM and when I upload the data I am noticing that the format that is displayed is YY/MMYY (example Flat file has 199810; the data after load is displayed as 19/9810).
The infoobject applied month is referenced to 0calmonth and has Peri6 as a conversion routine with 7 as output length.
Please help.

Hi,
You can use the following input formats for PERI6:
MM.YYYY
M.YYYY
MM.YY
M.YY

How to use Conversion Routines in Production Support?What is Conversion Routine?How it is Working in real time?

hi..
i'm not too sure abt it.. check out if the below helps ya.
you can create customer routines. According to OSS Note 41474 it is safe to create a function module that has the conversion exit naming standard (Begins with CONVERSION_EXIT*). You will get a warning that you can ignore. The important part is to have the first letter of your rountine name begin with Z or Y. That way you won't have a conflict with SAP. An example would be:
CONVERSION_EXIT_Z0001_INPUT .
i browsed n found these details as none had answered ur question.

Creating Special Conversion Routine

Hi!
what are the steps for creating Special Conversion Routine?
I have created FM CONVERSION_EXIT_VAKEY_INPUT via se37, is it a mandatory thing to create FM CONVERSION_EXIT_VAKEY_OUTPU?
Why my Special Conversion Routine VAKEY is not visible in the list among other routines? How to create it?
Will reward,
Mindaugas.

in my case it is ok to modify standart one and I have an access to SAP Market Place, but I am not asked for the key, when I press "Change" button, why?
And the source code becomes light grey with no possibility to change it....
Of course it is better to create z Conversion Routine, but how to do it?
I have created 2 FMs: CONVERSION_EXIT_VAKEY_INPUT and CONVERSION_EXIT_VAKEY_OUTPUT but this is not enough, because VAKEY is not in the list of among Conversion Routines.

Conversion routine PROJ in case master data doesn't exist

Hi gurus!
I have a problem with info-object 0PROJECT. It has a conversion routine PROJ, which converts the values nicely from external format to internal only if the master data for such project exists. If I use a interval variable in bex query the query user needs to give the upper value in internal value (for example Y3000 instead of Y-3000) in case he or she doesn't know if the value exists in database or not. That is understandable because of the logic of conversion routine PROJ (uses attribute project_ex).
But what explains the fact that query variable input value Y3000 doesn't give data of Y-3000, but only one smaller (Y-2999). To get data of project Y-3000 one has to give upper variable value Y3001.
Has anyone better understanding of this query/conversion behaviour?
Sari

Check the example here
http://help.sap.com/saphelp_nw04s/helpdata/en/dd/f470375fbf307ee10000009b38f8cf/frameset.htm
In master data updates, you can either load time-dependent and time-constant data individually, or together.
