You are starting of the Cuenta object record and there you have a button. Behind your button choose URL as content source and put in
/apex/Pagina1?cuentaId={!Cuenta.Id}

Cuenta.Id should be the record Id mergefield, when clicking the button you are opening the VF page Pagina1 and you pass the cuenta.id to the controller.
The controller creates a variable type String called cuentaId and sets it to the value received in the URL after ?cuentaid

then when creating the new object pre_factura_c, it immediately sets your lookupfield named cuenta__c to the id recieved and returns the page with the id prepopulated

Don't know how your page is called, but I guess you just want to pass in the AccountId
/apex/YourVFPage?acctId={!Account.Id}

and in your Visualforce controller start with taking in the id from the URL like so


String acctId = ApexPages.currentPage().getParameters().get('acctId');  

and the pass it to the field like

Cuenta__c = acctId;

Hello,

If your button call this Visualforce directly and this visualforce has as the StandardController the same object, you can try this way on your extension controller: 
public ExtensionController(ApexPages.StandardController stdController) {

     customSObject__c   obj = (  customSObject__c  ) stdController.getRecord();
     
     yourVFObject.customSObjectLookup__c = obj.Id;

}

Regards.

thank you for answer, I'm new at this.

the 2 obj have a lookuprela
cuenta__c --> pre_factura__c

my visual force page "Pagina1"

<apex:page controller="PruebaController" tabStyle="Pre_Factura__c">
<script> function confirmCancel() {
var isCancel = confirm("Are you sure you wish to cancel?");
if (isCancel) return true; return false; }
</script>
<apex:sectionHeader title="Crear Pre-Factura" subtitle="Pre-Factura"/>
<apex:form >
<apex:pageBlock mode="edit">
      <apex:pageBlockButtons location="bottom">
              <apex:commandButton action="{!PPagina2}" value="Siguiente"/>
              <apex:commandButton action="{!cancel}" value="Cancelar" onclick="return confirmCancel()" immediate="true"/>
     </apex:pageBlockButtons>
<apex:pageBlockSection title="Información Basica" columns="1">
            <apex:inputField value="{!prefactura.Sucursal__c}"/>
            <apex:inputField value="{!prefactura.Fecha__c}"/>
              <apex:inputField value="{!prefactura.Forma_de_Pago__c}"/>
</apex:pageBlockSection>
 <apex:pageBlockSection title="Cuenta" columns="1">
            <apex:inputField value="{!prefactura.Cuenta__c}"/>
</apex:pageBlockSection> </apex:pageBlock>
</apex:form>
</apex:page>

thank you so much, Jan Vandevelde
it works perfectly
Thanks

Glad to have helped! It wasn't easy with those spanish words in the code (confusing) but I guessed you would put the pieces I intended to explain together ;-) and you did!
Thumbs up!

can I bother you with another question?
I have the 3 pages, "Pagina1" "Pagina2" "Pagina3"

"Pagina1" is about Pre_Factura
"Pagina2" is about OT
"Pagina3"  is about Linea_de_detalle

​do you know if I can create more than one OT in this procces?

for example:
I'm in the page "Pagina1", and I finished to create the "Pre_Factura", so i clicked on the a button "next" that goes to the next page "Pagina2".
In the "Pagina2" i created the OT, but how can I create more then one?

I create a button add, and it works
I did this:

public class PruebaController {
    Pre_Factura__c prefactura;
    OT__c ot;
    OT__c ot2;
    Linea_de_detalle__c lineadedetalle;

    
    public OT__c getOT(){
        if(ot == null) ot = new OT__c();
        return ot;
    }

    public OT__c getOT2(){
        if(ot == null) ot2 = new OT__c();
        return ot2;
    }

    public PageReference PPagina1(){
        return Page.Pagina1;
    }
    
    public PageReference PPagina2(){
        return Page.Pagina2;
    }

    public PageReference PPagina3(){
        return Page.Pagina3;
    }         
    
    
    public PageReference cancel() {
        return Page.Pagina1;
    }
  
    public PageReference save() {
        
        insert prefactura;
        
        ot.Pre_Factura__c = prefactura.Id;
        insert ot;

        ot2.Pre_Factura__c = prefactura.Id;
        insert ot2;
        
        lineadedetalle.OT__c = ot.Id;
        insert lineadedetalle;   
    }   
}

It works, but only when I create two OT, when I create one OT doesn't work. By any chance, do you know a way that it will work?

 
Jan VandeveldeJan Vandevelde
Yes, your button calls the save method which will always create 2 OT from your code. If I get it right, the quantity of OT you will be creating can differ everytime. One time it will be only one OT, another it could be 2,3,4, 10 OT.

I would suggest you create 2 buttons: 1 is your save button and 1 "Save & New"
for the save button remove the OT2 code, for the save & new button call an action that only creates a new OT and you'll have to work with a list because you don't know how many records will be created when starting the page.
