Hi every one,
I need to create an interface to integrate a serie of Account’ data and Product’s data between Salesforce CRM and one management system.
I would predict 2 bidirectional flow that allow me to align the information from one system to another. For example: I could create a new Account in my management system and replicate a sub set of its data in the Salesforce CRM and viceversa, all in real time.
I think the use of WSs are as indicated.  
Do someone developed such integration? It could give me some useful tip to approach correctly the topic?

Thanks
Daniela
Hello Experts ,

We have an mobile application that uses salesforce SDK and is connected with salesforce. In a given scenario, mobile applicaiton syncs a child and parent one after the other. This was working fine untill now. They used to sync a parent using a temporary id which they self created and using that self created id they associated the child. However this flow has stopped working now all of a sudden and it gives an error like ParentObj__c: id vlaue of incorect type. 

Can anyone please advise?

Thanks in advance

Hi All,

This question may sound a bit stupid but i was very confused with the concept hence thought of posting here.

In an integration, how to we identify if its an http implementation or an https implementation.
As per my undertanding,
1. If the target endpoint starts with https and you are able to hit that url using required certificates from salesforce, it can be considered as an https implementation
2.At the other end, say for example i am implementing an integration between SAP and salesforce and SAP has set the transport protocol in their configuration as http with target url set to that of salesforce as "https//test.salesforce.com" and require self signed certificate from salesforce to be used while making outbound calls, in that case can this be considered as an https implementation?

Hope my understanding is correct.

Thanks in advance
Hello Experts,

We have a integration between salesforce and SAP via SAP PI. The external system is using HTTPS protocol and has asked if any other set up is required to have a secure connection while triggering outbound messages from SAP to salesforce.

This is when certificates come to my mind. We have both inbound as well as outbound integration between the systems.
I would want to know if:
1.While sending outbound messages from salesforce the certificate generated and provided by the external system has to be used in SOAP callouts. Correct?
2.When the external system sends outbound messages from SAP to salesforce, we need to generate and provide them CA signed certificate,which they will sign and send back to us. We then upload it in salesforce and the external system uses it while sending outbound messages from SAP to salesforce? Is my assumption correct?
3. Also i wish to know the difference between self signed and CA signed certificates and why should we not use self signed instead of CA signed?

Any help is appreciated

Hello,

I have a VF page say for eg: Page1 ,a text field T1 and a custom button btn1.
-User enters some text in T1 and navigates away by clicking on button btn1
-There after user is redirectted to Page Page2 and after he clicks on button btn2
-he again comes back to Page Page1.

Now the challenge is when he comes back to Page1, the text he entered in textfield T1 is lost. So how do i reatain this value for the end user?

I have separate controller for page2.So is that possible to retain such values even if my pages dont share the same controller?
Also i cant use passing params through url,since in my real scenario i have to deal with lists instead of a text field,

Any help would be highly appreciated

hi All,

i am facing some weird error with javascript custom button.I have javascript custom button that works for some record whereas for some it gives an error as "Unexpected identifier". However when i try to investigate this further, i see some issue with this particular statement highlighted below:-

if({!Account.Order_Block__c}==true || {!Account.Order_Block_on_sales_area__c}==true)
{
var x=confirm("{!Order__c.Business_Partner__c}"+' Business Partner is blocked for Order entry. Are you sure you want to continue?'); 
}

when the above statement doesnt work for some records, i have to modify it as under
var x=confirm('{!Order__c.Business_Partner__c} Business Partner is blocked for Order entry. Are you sure you want to continue?'); 
It seems to be a very lame solution to every now and then change the code with the previous version .Is there a permanent solution for this one?

Any help is appreciated

hi all,

i have a functionality wherein the pageblock table data is sorted when an appropriate column header is clicked.
Even though this functionality seems to be working fine,
it takes a lot of time to display the result on the VF page

Can anyone help me to make the records display faster on VF page?

below is my method i.e invoked whenever a column header is clicked

public PageReference doSorting()
    {
        wrapperLst.clear();
        sortOrder= sortOrder.equals('asc') ? 'desc' : 'asc';
        System.debug('***** sort order is'+sortOrder);
        List<Product__c> prodlst=runQuery();
        if(prodlst.isEmpty()==false)
        {
            for(Product__c pnew2: prodlst)
            {
                        OrderWrapper ow2=new OrderWrapper();
                        ow2.prodItem=pnew2;
                        ow2.oliItem=new Order_Line_Item__c();
                        ow2.isChecked=false;
                        wrapperLst.add(ow2);

        return null;
    }
    
    public  List<Product__c> runQuery()

Can anyone help me out on this?

We are currently trying to consume a soap web service exposed on a CastIron.
This WebService has a security certificate which does not allow us to communicate.
The certificate is signed by Symantec.
When there is no certificate active for the endpoint we consume, it works with no problem.

But when the certificate is active, while there is no problem calling the service from SOAPUI, when calling from SF we are receiving the following error message:
11:24:30.0 (325656624)|EXCEPTION_THROWN|[23]|System.CalloutException: IO Exception: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target 11:24:30.0 (537301785)|FATAL_ERROR|System.CalloutException: IO Exception: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target.

We are wondering if there is any extra configuration required we are missing. So far we have:
1. Add the remote site configuration where the endpoint is.
2. We use the correct endpoint URL, pointing to the https and 443 port.

We have done nothing about the certificate on SF side.
We do not understand if there is any configuation required concerning the intermediate certificate.
It is not clear to us if there is any further configuration required.

Please let me know what is missing or any documentation which explains very well what is required.
This is the documentation we have been using so far:

Dear all, Need your help urgently on below issue.
I have an object " Quotation" and we need to send quotation emaail template to Thai and English customers. The need is the picklist values like gender, marital status etc should be in Thai when the email goes to thai customer. It can be detected by the field " Preferred language" with values as " TH" or " EN". From " Translation Workbench" i can change the english picklist values to Thai.
But now the issue is , the users should always see the values in english while inputting. and in our database ( report etc), its always show english, as we need a consistent value ( e.g Male only not the Thai version of Male) its only when the quotation template goes to the customer it will change either to Thai or EN as per their preferred language. So, the Thai version picklist need to get stored somwhere in teh bckend.
If anybody can suggest how can i achieve this ? Thanks

hi all,

While my SAP colleage was trying to do a SOAP call from XI Server,an error pops up as below:

'com.sap.aii.af.ra.ms.api.RecoverableException: unable to create a socket: java.io.IOException: unable to create a socket'. Cause Exception: 'unable to create a socket

can anyone please help me out on this?
is there a need to open up any firewall?if yes then how?

Please assist ASAP
 

Posting this in order to help others who, months from now, might Google "OP_WITH_INVALID_USER_TYPE_EXCEPTION" and find this explanation.

 

We wrote an Apex trigger on the User object, to insert a custom object record anytime a user updates their Chatter status.  This was done to fulfill a client's requirement to audit all Chatter activity.

 

The trigger worked fine, until one day the client signed up some Chatter Free users.  When such a user tried to update their status, they got a pop-up with an OP_WITH_INVALID_USER_TYPE_EXCEPTION error.

 

We scratched our collective heads for awhile.  After all, Apex triggers run in "system mode," right?  That is supposed to mean that "object and field-level permissions of the current user are ignored."  And yet this trigger seemed like it was running in "user mode," enforcing restrictions based on who the current user was.

 

The root cause turned out to be that a Chatter Free user cannot be the owner of a custom object record, and SFDC by default sets the current user as a new record's first owner.  We discovered this when we realized, via experiment, that Apex triggers fired as the result of actions by Chatter Free users could definitely update an existing record, but were having problems creating records.

 

So the simple solution was to explicitly set the owner of the new record to some fully-licensed user prior to inserting it.
