How to check Le field is missed?

Hi,
When the protocol is T=1, I have problem with Le field.
When the card recieve Case 2 format command without Le(like '00B2010C' - Read Record) , how to check the Le field is missed?
I tried below but not working.
if(APDU.getProtocol() == APDU.PROTOCOL_T1 && apduBuffer[ISO7816.OFFSET_LC] != 0 && apdu.setIncomingAndReceive() != 0){
ISOException.throwIt(ISO7816.SW_WRONG_LENGTH);
I look forward your feedback.
Many thanks in advance!

Hi,
You should check the response from apdu.setOutgoing() to see what value was passed in as Le. This will return the number of bytes expected by the terminal.
You only need to call apdu.setIncomingAndReceive() if the INS expects data. You can also use it to ensure that there was no data passed in (returns 0).

How to check what fields are output from ABAP to smartform

Hi All,
I am working on a Zcopy of RLB_INVOICE smart form and need to check what fields are being output to the vendor_address window in the smartform.
I have examined the NACE setup and found "Medium -> printoutput", "Program -> ZRLB_INVOICE", "Form Routine -> "ENTRY_INS", "Form -> ZRLB_INVOICE", "PDF/SmartForm -> ZRLB_INVOICE".
Where would I find the code that shows the direct correlation between the driver program and a specific element of the smart form.
All I need to check is that all elements of the venfore address are being sent to the form as I am hearing reports that we are missing house number on the printed output.
Many thanks

Hi Meenakshi,
First you find out your driver program. Here in your case it is ZRLB_INVOICE. Then within that check where address of the vendor is found and is assigned to which import parameter of the smartform.
Check your smartform also. Find which all fields are being printed in that. If vendor_address window is an address window, then there will be uniques identifier passed to that window from the driver program.

How to check two fields are matching in a validator?

I have a "Password" field and a "Conform password" field. I like to check whether these two fields are matching in the password_validate(FacesContext context, UIComponent component, Object value) method. How to do that?
Thanks.

The actual problem is you can't get the value of one
component into the next component's validator
method.I do not find this to be true. For example, in the blog that I gave the URL to, you can see this code
public void endCalendar_validate(FacesContext context, UIComponent component, Object value) {
Date endDate = (Date)value;
Date startDate = startCalendar.getSelectedDate();
Here the validator for the endCalendar component is getting the value from a different component, the startCalendar component.

How to check the field existence in a string at Header level?

Hello,
I have a bunch of fields on my_form, just for example here in this posting I am using US state names ....., say for example,
I have 3 fields, their names are as below
1) NY,
2) CA,
3) TX
I placed a hidden a text field, its name is GFL (i mean, Grey Fields List), am using this GFL for my programming purpose
From the back end (in our case, its an ERP -SAP) am populating/filling this GFL field, say for example.... its data looks like, CA TX (i mean, am concatenating the state names with a seperation of a space)
( FYI.....Already i have some JS piece in my_form INITIALIZATION and docReady events for some other purposes)
Now, my requirement is as below,
1) LOOP all the FIELD objects (here they are as State names) of my_form , then check whether their name (NY) existing in GFL's data..........if exisitng (in our case, its not existing) pls. greyed out with readOnly.......... if not existing
(in our case, its not existing) then skip the coloring and readOnly, go to next loop / iteration / state / Field
Actually, i can achieve my requirement by putting JS in each field objet's INITIALIZATION event itslef as below, (but, i have around 200 feilds in my_form, hence i would like to put at HEADER level by generically looping all the field objects in my_form in one piece of code),
var myStateName = /NY/;
var returnValue = GFL.search(myStateName);
if(returnValue != -1){; // This state/field/object is found in the Grey Fields List, hence greyed out with readOnly
this.ui.oneOfChild.border.fill.color.value = "192,192,192";
this.access = "readOnly";
For some other requirement one of expert has provided the below JS in these forums, as below
function findNodes(vNode) {
 if (vNode.className === "field") {
 if (vNode.isPropertySpecified("name") === true) {
 if (vNode.getAttribute("name").search(/_U$/g) !== -1) {
 // Script to execute, when a match was found
 for (var i = 0; i < vNode.nodes.length; i += 1) {
 findNodes(vNode.nodes.item(i));
findNodes(xfa.form);
Actually, I tried to change the above JS as per my requirement, but its not working, pls. provide me correct JS as per my requirement
Thank you

Try this:
function findNodes(vNode){
 if (vNode.className === "field"){
 if (vNode.isPropertySpecified("name")===true){
 var myStateName=new RegExp(vNode.name);
 var returnValue = GFL.search(myStateName);
 if (returnValue!=-1){
 this.ui.oneOfChild.border.fill.color.value="192,192,192";
 this.access="readOnly";
 else{
 this.ui.oneOfChild.border.fill.color.value="255,255,255";//whatever colour is open access
 this.access="open";
 for (var a=0;a<vNode.nodes.length;a++){
 findNodes(vNode.nodes.item(a));
findNodes(xfa.form);

How to check a field in Message mapping wether it is Non Numeric?

Hi XI Guru's
I am totally new to XI world, Kindly help hopw can I chexk a field while doing message mapping whether the field is non numeric or not.
I dont find any built in function for the same.
If it is using UDF can some body help me in providoing a UDF for this.
Many Thanks
Arun

Hi Arun,
In SAP PI, all the XML contents by default treated as STRINGS.
So if u want to check whether the incoming field is numeric or not... the only way is to write a UDF code for the same.
the UDF will be,
1. At first
import java.util.regex.Matcher;
import java.util.regex.Pattern;
in functions.
2.UDF content:
input: field,container
output:boolean
Code
boolean return_Value;
Pattern p = Pattern.compile("[0-9]*"); // If u are using the decimals please change the regular expression accordingly.
Matcher m = p.matcher(field);
if(m.matches())
retuen_Value = true;
else
return_Value = false;
return return_Value ;
I hope this will solve ur problem....

How to check delta field in EDIDS table

Hi,
I have to create generic delta based on EDIDS (Status record) table. Since there is lot of data so i have to set delta point for this data-sources.
Could you please help to find delta field in this table?
Thanks & Regards
Devesh babu

Seems like there is no other fields which an be relevant delta.
check docnum is possible to use as numeric pointer.
Numeric pointer can be used when table allows for entering new records only.
if there is no delta relevant field, go with full load every time.
Use dso inyour data flow. so that we can introduce delta between dso to cube.
data flow like this
data source---> Every time full load to PSA--->You use delta or full load. it pulls latest request which is full to dso---> dso to cube, load delta dtp.
Need to delete the psa request before every load.
thanks

How to check a field value within an Internal table

Hi Friends,
My requirement is:
I have a line item of PO records, in that each line item of Plant field should not diffe with other line items. If it differs or say the records have different plant values line items, then I have to throw an error message.
Below example for better understanding.
lineitem Plant
010 ABC
020 ABC
030 XYZ
040 LKG
So, my report will throw an error like "All line items must be identical'.
How to do proceed it.Please advise.
Thanks & Regards
Sankar.

Hi Sankar
first you need to fetch all the values in one internal table from your PO.
After that create an internal table with only plant field and move all the plan values in this table.
let assume ITAB is a table with all the values. and ITAB1 with plant only.
wa_itab is the work area for ITAB and wa_itab1 is WA for ITAB1.
ITAB has all the values and ITAB1 has all the values only for plant.
delete adjacent duplicate from itab1 compairing plant.
loop at itab1 into wa_itab1. " this will fetch all the plant values in workarea.
read table itab into wa_itab where wa_itab-plant = wa_itab1-plant. " this will fetch only the values matching to the table itab1
if su-subrc <> 0.
message 'plants are not similar' TYPE 'E'.
elseif sy-subrc = 0.
write your code*.
endif.
endloop.
hope this will help you.
Thanks

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.

How to check for missing fields in the file?

Hi friends,
I have a file to file scenario in which if any of the fields have a blank value, i have to put the file back in the source folder. If none of the fields are missing, the scenario should work normally.
Can anybody tell me how can i check for the field lengths and if any of the fields are blank, how do i send it back to the original folder.
Waiting for your responses,
Divija.

Hi Divija,
>>how can i check for the field lengths
Since you need to basically check if the field has a value or not, i dnt think you need to check for the length of the field. Instead, you can use any one of the booloean functions available in the graphical mapping editor to check if the field has a value or not(filed value true or false)
>>how do i send it back to the original folder.
You can maintain a flag variable in the target structure such that if any of the source fields donot have values, the flag's value becomes 1 else it remains 0.
Now, you can check if the value of flag is equal to 1/0 in the bpm and accordingly send the data.
If in case, you donot want the flag to come in the target file that is loaded/sent from the bpm in the end, i think even tat can be taklen care of.
You can create two receiver communication channels and define one file adapter in each such that one has the destination as the actual target directory and the other has the original source directory as the destination.

How to check lock status of field in current document?

Hi,
How to check the status of field in current document(master agreement), that is whether its locked or not.
I locked "Publish to Supplier" checkbox after MA is saved first time. Now, I want to check the status whether this field is locked or not in the same document.
IsLockOwner( ) is not returning the correct value. Its not giving the current document field lock status.
Is there any way to get current document field status?
Thanks,
Saloni

Hi,
If I understand correctly, your requirement is to get the value of this field "Publish to Supplier on". It can be achieved by writing the below:
isVendorVisible = doc.getExtensionField("VENDOR_VISIBLE").get();
Meaning, if the box is checked, it will return a value = true and if not then false.
Hope this helps,

How do you spell check a field?

How are people spell checking their fields?
In searching around, I have only found (a) suggestions to yank the text into MS Word, do a spell check, then yank the resulting text into the field; (b) software from DC AL CODA that we aren't clear how they actually work (http://www.dcalcoda.com).
Specifically, my manager wants a tool that'll interface with Oracle like this: give a table name and a field name and be asked about each spelling error, much like an email spell check. The tool would change things as you ask, directly in the database. You wouldn't have to cut and paste into it and back to the db fields.
We aren't using forms. We use SQL*Plus, Quest Software's TOAD, and our own Java servlets (using JDBC to enter SQL statements).
I would love to hear how people do their spell checking.
Hopefully this is an appropriate forum for this question. There doesn't seem to be a general or SQL forum. Our database tables include a fair amount of text that shows up on Web pages. These are the fields we want to spell check.

I thought I'd reply to my own question since I found a workable solution, at least for our office which has MS Windows.
MS Access can connect directly to an Oracle data source. Access has a spell checking feature where you can select a field and spell check it. Below are tips and instructions for doing this.
TIPS:
It's surely a good idea to back up tables and be the only person or process changing those tables during the spell check.
One thing to watch for is whether the entire table comes in. At the bottom of the screen is a >* button which seems to get all fields. For large tables, you have to hit this button before you get the entire table.
Another glitch is that all of the given database user's tables show up in one list box -- makes for some painful scrolling, but all of the tables are listed.
A much smaller glitch is that if you widened any of the fields in the view of the table, when you close the window, it asks if you want to save the formatting. It has nothing to do with saving the data (that is automatic). It's safe to say no.
The spell check doesn't recognize HTML tags (asks about "br"s from tags) but seems to know to ignore things like "
How to set up an ODBC Data Source in Windows:
1. MS Start -> Settings -> Control Panel -> ODBC Data Sources (32 bit)
2. Drivers tab, scroll down and select Oracle ODBC Driver
3. OK
4. User DSN tab, Add...
5. Select Oracle ODBC Driver and Finish
6. Make up a data source name (example: src)
7. Enter a description for it
8. For Service name, put what your service name is (for an SQL*Plus connection, 'usr/passwd@svc', this is 'svc')
9. For UserID, put your user id (for an SQL*Plus connection, 'usr/passwd@svc', this is 'usr')
10. Ignore the rest of the fields, click OK
11. Another OK.
How to use Access to Spell Check an ODBC Data Source Field:
0. Install Access from (MS Office 2000).
1. Start Access (by the way, you might find it way down the list in Start -> Programs).
2. Open file, in the file type box, scroll to the end: ODBC Databases. You'll get a dialog.
3. Machine Data Source tab, select the name you gave it (src in step 6 above)
4. You'll be prompted for the password (for an SQL*Plus connection, 'usr/passwd@svc', this is 'passwd')
5. Select from the huge list of every table the table you want. Ok.
5.a. If the table has no key, you'll be prompted for the unique key from a list of all fields.
6. Double click the item that has just been added to the dialog that remains on the screen. It'll have a globe next to text like USR_TABLENAME. This brings up a randomly sized first chunk of the table.
7. To make sure you get the entire table, on the paging buttons on the bottom (|< < > >| >*), click >*. It may take a few moments to get a huge table.
8. Click the heading of the field (column) you want to spell check). This selects the entire column.
9. Hit spell check (ABC checkmark tool or Tools -> Spelling)
10. Check away. The changes are made immediately to the database.
11. Close the table display window.

How to check a checkbox field value in fw9 PDF form

Hi,
I got a PDF given form IRS (http://www.irs.gov/pub/irs-pdf/fw9.pdf). While creating a widget to this pdf form to sign it, I merged the custum data to those PDF form fields using API setMergeFields.
All the data fields are merged fine except the checkboxes. I tried by passing the values to the merge_fields array as 'On', '1', 'checked', 'checkbox(checked)' but no luck
What is wrong here in checking the chexbox field in this fw9 PDF or How to check a checkbox field in a form?
Thank you,

Hi Simon,
I re-added and edited the fields of fw9 form by pdf printer. While doing so, I made fields as ready only so that, the data cannot be edited in the form through the widget but will be merged the data to fields only be the code. Wherein Im using the widget only for signature but not for form filling.
Here, Im able to merge my custom data to all fields while creating widget but not to the fields of checkboxes. The checkboxes fields which are made ready-only are not allowing me to merge the value as checked by the API.
Please help me,
Thanks you,
