Check list field values using LINQ

I have to check if the CURRENT USER is already in the list USERS by comparing his AccountName to the list field ACCOUNTNAME.
If the USER is on the list I have to check if the field IsFollower is YES or NO and change it according to some conditions.
I think LINQ would be the correct way of doing this but I have no clue how to do that.
Any ideas pls, thanks

Hi,
Yes, you can query the list using LINQ.
You need to get the SPList Object firstly, and then you can query list item value using LINQ.

SV

Hi SV
what is your requirement first that should br clear.
i am giving you two UDF
1) i have written this uDF for string and comparing the field value XYZ
2) i am entering a string and its returning aa string which starts from the index of your input fixed length
int len = a.length();
String res = "";
String temp = "";
if ( len >= 10)
temp = a.substring(0,10);
if ( temp.equals("XYZ"))
res = temp;
else
res = "";
return res;
=======================================
String fixed = "ABCD";
String res = "";
int index = -1;
index = a.indexOf(fixed);
if (index == -1)
res = "NO INDEX FOUND";// or if u wanna set it as null res = "";
else
res = b.substring(index4,index12);
return res;
===
hope these may solve your problem

How to create a list of value using date?

We need to create a list on a report. The list consists of date. I have tried several times, but no luck.

Hi Charles,
I guess you have a user-parameter in your report and you need to define the LoV for the user parameter, so that the user can select from the LoV. In such a case you get REP-0782 if the datatype of column does not match the LoV of the parameter. Eg, if you have a query like
select * from employees where hire_date < :p_hire_date
And you want to build an LoV for hire_date, do the following:
1. Go to your user parameter > Property Inspector > Datatype > select "Date". If you select Character or Number, you will get REP-0782.
2. Now double click List of Values, choose "Select Statement" and type something like
select distinct hire_date from employees order by hire_date asc
If you don't want to use a Select Statement to build the LoV, you can write a static list of values, and even in this case Step 2 above should avoid the error REP-0782.

List of Values using page item variable

I know there has to be a simple solution to my problem but I cannot figure it out. Any assistance would be greatly appreciated.
I have a Shared list of values that I want to reuse on several of my pages. I have tried (I thought) all the variable possibilities but cannot figure out how to reference the page item in my list of values.
Original code:
select app_name d, app_sys_id f
from ops_application
where :P32_RADIO2 = 'Application'
union
select db_name d, db_id f
from ops_database
where :P32_RADIO2 = 'Database'
Doesn't work:
select app_name d, app_sys_id f
from ops_application
where 'P'||:APP_PAGE_ID||'_RADIO' = 'Application'
union
select db_name d, db_id f
from ops_database
where 'P'||:APP_PAGE_ID||'_RADIO' = 'Database'
I also have tried 'P'||v('APP_PAGE_ID')||'_RADIO'
'P'||&APP_PAGE_ID.||'_RADIO'
'P&APP_PAGE_ID._RADIO'
'P'||:APP_PAGE_ID||'_RADIO'
Thanks,
Gayle

Gayle,
I haven't tried this, but what about
where v('P'||:APP_PAGE_ID||'_RADIO') = 'Application'That should allow you to build up the name of the page item dynamically, and then test the value...
A lower-quality solution would be to use an application item rather than a page item, as then you'd know the name ahead of time.
Let me know if this works,

Extracting a distinct list of values using the Index formula

In Xcelsius, I am trying to retrieve a distinct list of values from data imported using the Reporting Services button.
In the spreadsheet I am using the following formula:
=INDEX($A2:$A831,MATCH(0,COUNTIF($B$2:B2,$A2:$A831),0))
The above formula works correctly in Xcelsius, but when I select the preview button the values change to #N/A.
Please could you advise on why this does not work?
Many thanks,
Natalie

Hi Natalie,
First, you have to be aware of the fact that Xcelsius "simulates" an Excel function. When you are in design mode, the actual "Excel" (MS code) functions are executed. But when you are in preview mode (or export to a swf), all Excel functions are simulated (Xcelsius code).
The fact that your function works in design mode but not in preview/export may point to a bug.
But there are also certain assumptions (to address speed/efficiency) on the Xcelsius code which may cause the preview to fail. One such assumption is that on the VLOOKUP function, Xcelsius does not recalculate formulas in the index column of the VLOOKUP table array - if the index column contains formulas, the index column will always remain in the initial state (will not dynamically recalculate).
Also, not all features on a supported Excel function works. For example, array formulas are not supported.

List of Values using WeCheckbox

I attempted to apply the same principles in using shared variables within a subreport to populate the values for WeCheckbox function. Although I was able to get the list of values to populate as desired, something strange happened when I tried to use the name of the variable within WeBuilder function. When I referenced the exact variable, it doesn't show up on the report. However, if I just use "Checkbox" in the WeBuilder function, everything displays perfectly. The obvious problem is that I can't capture the selected checkbox with a Submit button, as it never displays that it is capturing the user selected checkbox when passing parameters to the target report. Is it possible to use a list of values to populate the WeCheckbox function and also be able to pass the values to a target report?

hello Eric,
i am not sure if i understand the issue. can you please change the WEBuilder's debugging mode to "2" so that it will display the url that it is generating...what is the url that is being generated and what is wrong with the particular url when the end user selects a checkbox and presses submit?

Check of field values from the delivery address in PO

The customer likes to check a field from the delivery address (f.e. NAME1) before the PO is saved. I looked for Userexits but diddn't find any. The only way sees to be a modification. The question is where to modify...

Name 1 fields is under Delivery Address tab for PO line item details. -> This was not my question
It can be maintained i n SPRO itself by defining Address for store locations . -> This was not my question
User have to put storage location in PO line Item itself then Name 1 field will displayed values in SPRO -> This was not my question
It has to be CHECKED by the system if the content of field NAME1 (from wherever the system gets the address) equals to a special text. There must be a statement such as:
if ADDR1_DATA-NAME1 eq '1234657678' ....
The problem is to identify the right include where i can get the relevant fields.

Issue facing : Deletion of Qualified Look up field value : Using Import Map

Hi All,
We are having qualified multi-valued look up field in the main table. Using import map for the main table record update, we are trying to delete the qualified look up field value. But it is not working.
Please guide on how you have achieved this.
One approach is to supply NULL value, though I am not sure or have tried this.
Regards,
Ganga

Hi Ganga,
I assume that you are trying to delete the Qualifier values for the Qualified look up table. The only possibility is to pass the Null values to the already Existing records in the Main table. Please note that if you are passing one Null value only one record will get deleted. So you will have to pass the Null values equivalent to the number of values for the Multi Valued Qualified table.
Kind Regards,
Thamizharasi N

Lenfinkel

Hi LenFinkel,
May I know what is purpose of this requirement, as olaf said,you may parse the T-SQL code (or the execution plan), which is not that easy.
I have noticed that the condition values in your Stored Procedure(SP) are hard coded and among them there is a date values, I believe some day you may have to alter the SP when the date expires. So why not declare 3 parameters of the SP instead hard coding?
For multiple values paramter you can use a
table-valued parameter. Then there's no problem getting the values.
If you could elaborate your purpose, we may help to find better workaround.

Reading deleted field values using change pointer

hi
i am triggering DEBMAS06 using change pointer technique for XD01/02/05/06 transactions.
now when i delete data(make nulll values) in partner functions the generated IDOC is not showing the complete field itself.when i am deleting the field value and making it null the IDOC must send the fields with null values.but unable to trace out how to do this.
can anyone let me know how to handle this situation?
and i have extended DEBMAS06 with customer hierarchy data i.e. KNVH.i have written change pointers.now how can i populate these fields into my extension?

Hello Moorthy,
1. This message function in the Idoc is populated as 005 then it should replace the entrire values while posting,
2. To populate KNVH extension you have to populate this only if you have KNVV data.. so you can either create enhance menti perfrom FILL_SEGMENT_E1KNVVM i(nf Function moduler MASTERIDOC_CREATE_DEBMAS) inclduer LVV01F01. or you can write the logic in BAdi CUSTOMER_ADD_DATA->FILL_ALE_SEGMENTS_OWN_D or in user eixt EXIT_SAPLVV01_001.
