Using the MSG_* Function Modules

Hello,
I want to use the MSG_* function modules (e.g. MSG_OPEN, MSG_ACTION ...) and the MAC_MSG_* macros in my own programs, but they are not documented. Are there any docs about it?

Stefan

Is it necessary to use the standard function modules always?

Hi All,
Suppose i can retrieve the BUSINEES PARTNER ID from the table BUT000 with the help of 'BP_GUID' field through a select query statement.
Now is it necessary to use a standard function module to retrieve the same data. what about the performance? which is the better solution. to implement our own code or to use the function module available.
Please someone clarify me about this issue.
Regards,
Sharry.

If you'd ask the question in general it's obvious that there is no good answer as it always would depend on the circumstance. However, as you've posted your question in the performance tuning forum, let's look at your question in this context first. I think it's fairly safe to say, that in almost 100% of the cases a standard function module will not be as fast as any well implemented and custom tailored code. If in doubt, just try reading the code of the function module you want to read; most likely you will find lots of unnecessary fluff in there, often they read data that you don't even need.
And as far as buffering is concerned, that can also be an issue. E.g. let's say you do a massive read of distinct business partners and you only need the data once for each partner. Obviously buffering is silly in this case and it might even slow down your program, because the implemented buffering is not necessarily well implemented. I've come across a few cases, where the buffer tables where standard tables with no efficient read access (so no sorted table or hash table) and once tons of data were buffered, it actually took a moment to look up if the record already was buffered (just to find it wasn't there yet).
Now most of the times this slowdown is not an issue as the lookup is still fast compared to the (usually) prevalent database accesses with their slower IO timing. But another factor to consider is memory consumption and why buffer data in memory (and waste it), if you can't use the buffer anyway? So when I do use standard function modules, I usually try to see what they retain in global memory, to better understand if I need to call some initialization/clearing/refresh function...
Note also that often you need to process lots of data, but don't find a standard function module for "mass access", so you need to read your object one by one. Obviously that's another good candidate for implementing your own queries, where you can process the data in packages.
So what might be the reason to use a standard function module? Well, often it's required because the logic is so complex that it would take you too much time to implement it (not to mention that we often simply don't know all the logic that's coded in there). Another advantage is that you might get independent of the data model. E.g. for IDoc interfaces SAP switched in some release the tables where the data is stored. So if you had coded your own queries to get IDoc data, they wouldn't have worked after this particular release upgrade. The standard function on the other hand, checks both the old and new tables, so by using it you would have been fine.
The one major caveat I'd give though is to always check whether the function module is released or at least documented to some degree. I.e. if it's not released, SAP won't support it and does not guarantee that the interface or logic stays the same. In my experience lots of functions I do want to use are not released (or documented), but I will still use them because they seem to be the best alternative in certain scenarios.

Has anyone used the FORMAT_MESSAGE function module in ECC 6.0 ??

We've upgraded to ECC 6.0 and now I have a BDC program using FORMAT_MESSAGE function module that has a problem. The number after the & (&1, &2, &3, &4) in the function mod isn't replaced, it stays as a literal and only the & is replaced with a valid value which it then passes back to the program.
Anyone else have this problem? Any ideas how to fix?

Seems like an authorization problem. Call SU53 immediatly after the failed function call and check with your security or system administrator (authorization object S_LOG_COM).

Raj.S

Hi Raj
Function Modules
Function modules are procedures that are defined in special ABAP programs only, so-called function groups, but can be called from all ABAP programs. Function groups act as containers for function modules that logically belong together. You create function groups and function modules in the ABAP Workbench using the Function Builder.
Function modules allow you to encapsulate and reuse global functions in the SAP System. They are managed in a central function library. The SAP System contains several predefined functions modules that can be called from any ABAP program. Function modules also play an important role during updating and in interaction between different SAP systems, or between SAP systems and remote systems through remote communications.
Unlike subroutines, you do not define function modules in the source code of your program. Instead, you use the Function Builder. The actual ABAP interface definition remains hidden from the programmer. You can define the input parameters of a function module as optional. You can also assign default values to them. Function modules also support exception handling. This allows you to catch certain errors while the function module is running. You can test function modules without having to include them in a program using the Function Builder.
The Function Builder also has a release process for function modules. This ensures that incompatible changes cannot be made to any function modules that have already been released. This applies particularly to the interface. Programs that use a released function module will not cease to work if the function module is changed.
Check this link
http://help.sap.com/saphelp_nw2004s/helpdata/en/9f/db988735c111d1829f0000e829fbfe/content.htm
You can execute function module in SE37ie you can perform the activiites defined in the function module by executing it.
By deleting BOM you mention the FM name in se37 and execute. In some function module it will ask input parameters as developed in the program , you have to give the input parameters and execute.

How to create the INBOUND Function Module for INBOUND IDOCs

Hi Friends,
Can any Suggest me How to proceed to Create an INBOUND Function Module for Processing the INBOUND IDOCS
which are recieved from XI Server ?
I am working in SAP-ISU
Here i will recieve the INBOUND IDOCs for the Meter Reading Orders.
We have a Standard INBOUND FUNCTION MODULE
IDOC_INPUT_ISU_MR_UPLOAD
which Uploads the Meter Reading Results.
I copied the Same function Module into ZIDOC_INPUT_
and working on it.
Can any one suggest me, whether i am going in correct way or not.
In IDOC_INPUT_ISU_MR_UPLOAD Inbound fun module,
BAPI_MTRREADDOC_UPLOAD is used to Update or Insert the Meter Reading Results,
My requirment is to Insert and Update the Meter Reading Orders which are Inbounded from XI.
Can I Use the Same BAPI
BAPI_MTRREADDOC_UPLOAD
to Update the below fields,
EABL-SERNR
EABL-ZWNUMMER
EABLG-ABLESGR
EABL-V_ZWSTAND
EABL-N_ZWSTAND
EABL-ABLHINW
EABL-ZSKIPC
EABL-ADAT
EABL-ATIMTATS
EABL-ADATTATS
EABL-ATIM
EABL-ZMESSAGE
EABL-ABLESER(Meter reader number)
Kindly Suggest me,
Thanks in Advance,
Ganesh

Hello Ganesh
I think you are going completely astray with you z-function module for IDoc processing.
If you look at TABLES parameter METERREADINGRESULTS (type BAPIEABLU ) of BAPI_MTRREADDOC_UPLOAD you will find many of the requested fields already:
EABL-SERNR => BAPIEABLU-SERIALNO
EABL-ZWNUMMER =>REGISTER
EABLG-ABLESGR
EABL-V_ZWSTAND
EABL-N_ZWSTAND
EABL-ABLHINW
EABL-ZSKIPC
EABL-ADAT
EABL-ATIMTATS => ACTUALMRTIME
EABL-ADATTATS => ACTUALMRDATE
EABL-ATIM
EABL-ZMESSAGE
EABL-ABLESER(Meter reader number)
Field EABL-ZMESSAGE appears to be custom field (at least I cannot find it on ECC 6.0). If this field was added using include CI_EABL then you probably can get these values into the BAPI using the EXTENSIONIN parameter.
Check routine CHECK_UPLOADRECORDS in the BAPI which allows two extension structures:
- BAPI_TE_EABL
- BAPI_TE_EOSB
Not surprisingly BAPI_TE_EABL contains the include CI_EABL.

Use of g_posting_glpct function module

can anyone explain the use of the following function module.
1. g_posting_glpct
2. message_prepare
3. k_costs_plan_interface_period

Hi
g_posting_glpct - used to Posting values into GLPCT table
message_prepare - this Fun module is similar to FORMAT_MESSAGE which is used to format the messages into a string and to display.
 k_costs_plan_interface_period - used to Transfer Cost Planning with Period Values
Functionality
The function module transfers activity-dependent primary cost planning for cost centers to orders and projects, and revenue planning to cost centers. You can process only one object type per call up -- for example, you must define transfers to cost centers and to orders in two separate operations. The transfer of individual plan records uses table IRKU01JA with structure RKU01JA. The module treats periodically occurring plan values.
The module import parameters (fiscal year, version, and so on) are valid for all plan records in the table and appear automatically in the table entries. Identically-named fields in table IRKU01JA need not be filled. Because the structure applies to other planning transactions and different planning objects, you must supply the relevant information for the relevant fields only (see table IRKU01JA).
If the transferred plan values do not appear otherwise (see parameter DELTA below), they appear as new plan totals values. If line item update is active for the version in question, the system creates line items for new plan records and corresponding difference line items for previously-created plan records.
Transfers take place after tests for valid plan records. The module can issue an error message for invalid records at the end of processing, if so desired.
Reward points if useful

Where should i call the rfc function module? in xi or in r/3

where should i call the rfc function module?
for the synch scenario: file < -- > xi <---> rfc
i know the type of rfc is tcp/ip; but i'm not sure with the followings,
and with some trials i can not even see any message via rwb even all the setting
can be activated without errors.
where should i create the rfc destination? in r/3 or xi
where should i call the rfc via abap program? in r/3 or xi
i guess the calling program should belong to the different server with the rfc itself....
so confused....
Thanks for your reply!!
Jun

if i create the destination in xi point to r/3, then i call the rfc use the destination in r/3 right ?
The call doesnt use the destination in R3. XI has the RFC destination which is just used to connect to the R3 system
but where i need to create the fm via se37? in xi or r/3 ?
In R3

but mail is not generated. if I run the same function Module in foreground mail generated successfully....
can anyone please tell me the reason behind this.

Hi i realise that The LIST_TO_ASCII thing is not working correctly in background because the the list-processing in beckground is working not the same as in dialog i think.
I can only get the last page of the list out when running in background. Any solution to this?

Use of this function module

hi,
can anyone explain the use of this function module, i coudn't find any documentation .
This function module prints the data selected in selection screen.. but i want a breif explanation y we use this and wat for is this....
FM_SELECTION_CRITERIA_PRINT

Hi,
1. Suppose the requirement is to know the parameters/select-options selected on the selection screen, on the list output (report).
Because once we are on the report output , we wouldnt know the selection parameters made. The only way is to go back & check. Instead of going back we can use this FM to know even when we are on the o/p.
2. Also to take a print of both the report output& selection parameters.
Reward if useful.
Thanks
