The Group_ZA comes 'n' number of times and D02_ZA comes sometimes 5 times and sometimes 6 times etc.,
ZA_01 field can come with 5 to 6 different values like 'QA','QD','QN' etc., sometimes ZA_01 comes only 3 times QA,QD,QN.
if ZA_01 = 'QA' then only we need to pass   ZA_02 value on to ''UnrestictedUseQuantity'' (target side),
I mapped the fields, the vlaue ZA_02 passing properly on to 'UnrestictedUseQuantity' when D02_ZA comes 5 or 6 times, all the times 'QA' value comes into ZA_01 field. In case if QA value missed or doesn't come from source, the Target side ' 'UnrestictedUseQuantity' field last value comes into last but one.
Ex: QA value is in 3 times, but I have 4 source message on top. values comes into target side like
20
20
20
suppose to come like
20
20
-- (Space)

Petre:
If you want to use standard functions then you try this:
If-->currentdate -OR- Constant(01.02)
currentdate -OR- Constant(02.02) --> OR -->
currentdate -OR- Constant(03.02)
Then give some output
Else give some output
So give the output for the first two conditions to another OR and the result of the third to the same OR. So whenever the condition is true in any of the condition you will get the THEN value else you will get the ELSE value.

How to use or function in Message Mapping?

Hi! I was wondering if anyone can show me how to use the or function.
Im trying to match the current date to three possible values so i need three or functions.
EG. if ( currentDate == 01.02 || currentDate = 02.02 || currentDate = 03.02 ) {
do something;

Using useOneAsMany function in Message Mapping if subtree is optional

Hi,
I am trying to develop a message mapping for the following case:
In the source message, there is a value "Value1" which is on the same level as a subtree "Struct2" which can occur 0..unbound times
In the target message the value "Value1" has to be part of that subtree, so it has to be copied for each occurence of "Struct2" in the source message
For the case that the subtree has cardinality 1..n there are some examples on the web, e.g. useOneAsMany (SAP-Bibliothek - Partner Connectivity Kit). But that does not fit my case. The subtree in the source message is optional here.
See a screenshot of the message mapping and my solution for the mapping of "Value1" below:
All other values are mapped 1:1.
Sadly, this solution does not work when "Struct2" has cardinality 0..unbound, for 1..unbound it works perfectly. Here is my example:
When I try the mapping, I get the following error message:
That is true. The first queue of the useOneAsMany function has more values than the second. But I don't know how I can fix it, so that it works for my example. Can anyone give me a hint please?
Setup is AEX 7.31.

Hi Stefan,
You can use this mapping.
And for Struct2-Value1

Hope this helps,

Node functions in Message Mapping

Hi,
Could someone help me with some good exercises for node functions such as splitbyvalue, collapsecontents, removecontexts.
I am a newbie to these functions and have absolutely no idea on how to use them. Would appreciate if someone could give very detailed examples to these functions in a step by step manner, so that I can create them just by following your instructions.
Any links to video presentations are welcome too.
Cheers,
S

Hi ,
For a fresher, the informationa and examples given in the help.com would be more helpful and it will help you in building string fundamentals. Once your basics and funcdamentals concepts becomes strong then you can go for more complex exmples. Here is help.sap link where you can leran Node functions of MM of PI.

How to use analytical functions inside a mapping

Hello everybody. Here Isend you a trick that we are using for two years.
If you want to use a function (for instance :ROW_NUMBER() OVER (PARTITION BY ... ORDER BY ...)) inside a mapping you must create an expression with in the INGRP1 the fields you are going to use in the window function and in the OUTGRP1 the function you want. Create an Out -attribute with the expressión and link it to a distinct operator (using a "distinct" you encapsulte the sql and you will be able to use the function inside a filter - in the where clause.). The distinct can eliminate some register (depends on the function). If you validate the expression an error will appear (don't worry about that, the mapping will be ok).
But there is a limitation, you will not be able tou sum over, min over, max over (it detect that they are aggregator functions). Other limitation: the debugger doesn't run with this kind of functions.
Please publish this information on "The Warehouse Builder Utility Exchange". Mi email is [email protected] (if you need more information)

It is possible to add SUM, MIN, MAX functions also to OWB releases prior to Paris - You have to put them in double quotes - write "MIN" "MAX" "SUM" etc. The rest of the rules (adding cut-off operator after the expression - as DISTINCT, or UNION ALL) is analogical to with ROW_NUMBER()
That means You can create mapping with following functionality:
SELECT
sum (salary) over (partition by DEPARTMENT) department_salary,
salary,
employee_id,
employee_name
FROM employees_salaries
writing it this way in OWB:
SELECT
"SUM" (salary) over (partition by DEPARTMENT) department_salary,
salary,
employee_id,
employee_name
FROM employees_salaries

Hi,
The RfcAdapter trys to find a Sender Agreement for this RFC call but the lookup failes. The values used for this lookup are:
Sender Party/Sender Service: The values from Party and Service belonging to the sender channel.
Sender Interface: The name of the RFC function module.
Sender Namespace: The fix RFC namespace urn:sap-com:document:sap:rfc:functions
Receiver Party/Receiver Service: These fields are empty. This will match the wildcard

FILE to IDOC using node functions; IDOC parent, child segment

I have file with 10 recors.
Each record has f1,f2 (two fields)
The target IDOC segments are
E1PARENT1 occurance 0 to 99
E1PARENT1-field_p1
E1PARENT1-E1CHILD1 occurance 0 to 5
E1PARENT1-E1CHILD1-field_c1
I have to map
FILE field1 to E1PARENT1-field_p1
and
FILE field2 to E1PARENT1-E1CHILD1-field_c1
I tried
RemoveContext -> SplitByValue(value change) -> CollapseContext ->E1PARENT1
RemoveContext -> SplitByValue(value change) -> CollapseContext ->E1PARENT1-E1CHILD1
With above i'm getting output
a) parent IDOC segment E1PARENT1 repeated 10 times (source FILE got 10 records) .. .This is correct
b) The first parent segment E1PARENT1 got 5 child segments E1CHILD1. -- this is incorrect
c) The second parent segment E1PARENT1 has NO child segments E1CHILD1 -- this is incorrect
I want
first parent segment E1PARENT1 to have 1 child segment E1CHILD1 having 1st record field2 of input FILE
2nd parent segment E1PARENT1 to have 1 child segment E1CHILD1 having 2nd record field2 of input FILE
3rd parent segment E1PARENT1 to have 1 child segment E1CHILD1 having 3rd record field2 of input FILE
I think by changing occurance (ECC value is 0 to 5) of child IDOC segment E1PARENT1-E1CHILD1 to 1 could solve this issue. (I tried to change the text file, but it is no confusing where to change using Notepad). Basically i don't know how to control the queue context of CHILD segment of IDOC matching with PARENT segment of the IDOC.
Any better alternative. Please help. Thanks

This is the IDOC target
E1PARENT1 (o to 99 occurance)
E1PARENT1-field_p1
E1PARENT1-E1CHILD1 (0 to 5 occurance)
E1PARENT1-E1CHILD1-field_c1
I resolved using standard function of message mapping. The mistake was SplitByvalue(value change), when changed to SplitByvalue(each value) got desired result. Here is the mapping to benefit others. Please correct or add if any, thanks.
a) Target - Parent segment
SOURCE-RECS->RemoveContext -> E1PARENT1
SOURCE-RECS-F1->RemoveContext -> E1PARENT1-field_p1
b) Target - Child segment
SOURCE-RECS->RemoveContext -> SplitByValue(each value) -> E1PARENT1-E1CHILD1
SOURCE-RECS-F1->RemoveContext -> SplitByValue(each value) -> E1PARENT1-E1CHILD1-field_c1

IDOC to FILE(xml) graphical mapping using node function createIf

Greetings All,
            My Scenario is Idoc to File(XML)
Target Structure is
                       MO_MAT_LAN....................(0: unbound)
                            LAN_KEY.......................(0 :1)
                            DESCRIPTION.................(0 : 1)
Source MATMAS Idoc
                       E1MAKTM.........................(0 : 99)
                            SPRAS_ISO..................(0 :1)
                            MAKTX..........................(0 :1)
initially i had mapped E1MAKTM----->MO_MAT_LAN but i dont want target node MO_MAT_LAN to be created when the SPRAS_ISO is equal to EN
I have tried using node function createIf but the node is geting created only once although the input stucture is having occurance more than 5.
Can anyone please help me to achive this.
Many thanks,
Rohit

U have to use:-
SPRAS_ISO mak the context to E1MAKTM compare (Use equals) it with Constant function EN out put to be given to If without else and in then Give E1MAKTM and map out put of If node to MO_MAT_LAN.

How to validate a date in message mapping

Hi experts,
how to validate a date in message mapping. For ex: if date comes as 2008/02/31, then file it shold not get processed.how to achieve this in message mapping. Please help .
Thanks&Regards,
Reyaz Hussain

Hi,
There are few simple ways for date validation as follow,
1.If you would like to handle it in XI only, then in message mapping you could verify about it with the help of generating smart exception.
For e.g in mapping there is one Date conversion API i.e. somthing DateTransformation It converts the incoming date format to required format. Here give the date format i.e expected from Sender File.
If in case the format miss-matched then it will create the exception.
You could handle this exception with the use of [Alert notification|http://help.sap.com/saphelp_nw04/helpdata/en/2c/abb2e7ff6311d194c000a0c93033f7/frameset.htm] and could be even able to notify to sender system about it.
2. The another solution is easy for SAP synchornous communication --If you are passing the file data to SAP, then you could use below function modules to verify date format in receiver RFC/BAPI or inbound IDOC program. If the sy-subrc is not 0 then don't process further.
CONVERT_DATE_FORMAT
ISU_DATE_FORMAT_CHECK

Hi
The use of Standard Parner functions are as follows:
1. Ordering Address (OA): The PO will be sent this vendor and not the main vendor.
2. Goods Supplier (WL): In case of return deliveries, Goods will be returned to thsi vendor's address
3. Invoicing party (RS): The payment will be made to this vendor.
Hope this clarifies.

Hi,
Yes, you can do that with aggregate functions.
First, do a sub-query to retrieve all the salaries (in descending order), then say "WHERE ROWNUM <= 5" in the main query. Use the aggregate SUM and AVG functions in the main query.
Analytic functions are easier to use for jobs like this, once you get familiar with them. If you're not leaving the field this month, then it's probably worthwhile for you to get familiar with analytic functions.
