What is meant by matn1 conversion routine in info object

hi,
Can i know the exact meaning and usage of matn1 (type of conversion routine) in the infoobject level.
thanks in advance

Hi Sankar,
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.
Check the info here:

What does CUNIT, ABPSP & ABPSN conversion routines do?

What does CUNIT, ABPSP & ABPSN conversion routines do?
There is no help on SAP documentation on how these conversion routines work?Can someone tell me in simple english on how to they the padding logic.
Something like if all numeric then pad spaces on the left side etc
thanks
Rao

Hi Rao,
I can help you with CUNIT. SAP manages units of measure in an internal and external format. That its, when it is saved in database, it uses a code (for example for units it uses ST), and when it shows you the value, it uses another one (in this case UN). So, what basically does CUNIT conversion routines (A.H.P mentioned the function modules) is to switch between those formats.
Hope to help!

What are the commonly used conversion routines apart from alpha conversion?

hi all,
Can any one let me know the commonly used conversion routines apart from alpha conversion routines ?

There are lot of conversion routines, like
BUCAT Conversion Routine. eg. The BUCAT conversion routine converts the internal presentation of the budget type
(0BUD_CAT) into the external presentation (0BUD_CAT_EX), using the active entries in the
master data table for the budget type InfoObject (0BUD_CAT).
see the link below for all the routines.

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

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.

WBS element conversion routines

Hey guys,
I recently added PS_PSP_PNR to 2LIS_11_VAHDR in order to extract the WBS element from the sales document header. So far so good and everything works fine. In the extractor checker I get the data as expected e.g. 'S-00017.02.09'.
The problem occurs as soon as the data is transferred to BW. In the transfer structure I see that PS_PSP_PNR har conversion routine ABPSP that converts the WBS from external format CHAR(24) to internal NUMC(8). And this is what is causing me the trouble! In the PSA the WBS from above is converted to '00029788'.
I tried several different approaches. If the field is mapped directly to 0WBS_ELEMT the value '00029788' is obviously also written to the DSO and further up the data flow.
I tried coding an ABAP routine in the transfer rules which does not seem to work:
call function 'CONVERSION_EXIT_ABPSP_OUTPUT'
exporting
input = TRAN_STRUCTURE-ps_psp_pnr
importing
output = RESULT.
RETURNCODE = 0.
ABORT = 0.
Since the routine above did not help me at all I tested the FM in SE37 and it does not return any values for '00029788'.
Any clues on this? How to proceed?
BR
Stefan.

Well... Didn't want to wait any further for an answer, so I appended PS_POSID to the extract structure and filled this field in ZXRSAU01. In the exit I used 'CONVERSION_EXIT_ABPSP_OUTPUT' to convert to the correct format.

Conversion routine for time key figure

Hi,
i have a filed in datasource which has length 5 ( of numeric char ).it may be coz time can be represented as "hh:mm" which has of course of length 5.
this particular field is mapped to a key figure of type time ( which is only 4 numc ).
because of this mismatches transfer rules are not getting activated.
what i need to do now? is it neccessary to write a conversion routine again?if yes, can any body write here the code required for it?
thanks,
Ravi

Hi Ravi,
Assuming time comes in 'HH:MM' , colon placed explicitly , Code should look like ...
bwtime(2) = r3time+1(2) .
bwtime2(2) = r3time3(2).
Where BW_Time stands for info object.
R3time stands for transfer structure field.
Normally time field is of type numc lenght 6 ( HHMMSS) and inthat case should not be any issue when used in BW system.
Hope that helps.

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.

Conversion Routine problem

Hi,
In one of the info object there is a conversion routine. So, when the query is executed in BeX Query Analyzer the result is comming correct i.e. if in the database the value of info object is 0001234 then at display it is coming as 1234.
However, in case if its value is "STEP" in database , at output "Not Assigned" is comming. Dont know what is happening. If anybody already encouter this problem please help.

Hi,
It is not in the hierarchy.
I am using alpha routine so as to remove the leading zeros at the time of display.
There are two info objects, both are same, the only difference between them is one info object is having alpha routine and another one is without it.
The one info object without any routine is displaying values correctly but the another one with aplha routine is displaying 00123 as 123 but also displaying STEP as Not Assigned.

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..

Changes is special conversion routine not taking effect

I changed a special conversion routine specified in a conversion rule(BD79) with a rule type copy sender field.
I made the required changes to the function module CONVERSION_EXIT_&_OUTPUT and activated it but still the outbound Idoc suggests that the changes are not taking effect.
Can someone suggest what may be the reason for this?
