For Zoho Services only:


I'm actually part of a bigger team at Ascent Business Solutions where we have support technicians and project consultants. Support is for smaller technical fixes but this can include developments, reports or integrations; depending on the size of the task. Projects are for more time-consuming developments such as revamps of the Zoho Suite of apps or on-site training. The advantage of a team is that if I am out-of-office for a day or so, there is always someone at Ascent Business Solutions who can deal with any queries/issues you may have.

Our support rates can be found and purchased at http://ascentbusiness.co.uk/zoho-support-2. A support bundle doesn't have an expiry date. So whether we can do what you want within the bundle and a year later need further support, if there are minutes left on the bundle then there is no additional charge.

Our project rates for bigger developments can be found at http://ascentbusiness.co.uk/crm-solutions/zoho-crm-packages-prices and will involve a dedicated project consultant along with developers who will hold your hand through the development process.

If you want help building a solution for one of the Zoho Apps in the Zoho Suite, contact us on 0121 392 8140 (UK) or by email at info@ascentbusiness.co.uk. You can also visit our website at http://ascentbusiness.co.uk.

I regularly build and specialize in 2-way API integrations for Xero, Shopify and eBay.

Zoho Creator: Populate a Multi-Lookup

What?
This is a very quick article with a code snippet on how I added to a multi-lookup field.

Why?
Using a multi-line or text is possibly a quicker solution and when using a desktop interface, you can parse the multi-line into a nice HTML table. But on a mobile device, it's somewhat better to use the built-in interfaces provided by Zoho Creator.

What I really needed was a way to display the line items from a package slip taken from Zoho Inventory. I'd prefer if it was included in the list view or a Zoho Creator report.

How?
We would think it similar to a picklist/dropdown where you simply add an option to the picklist and then specify which of the options are selected. In this case, simply giving it the IDs should work... but it doesn't.

Assuming my multi-lookup field is called "Zoho Inventory Package Slips" and I'm adding these to a Creator form called "Appointment", my code should be something like the following:
copyraw
//
// get 100 most recent appointments where this field hasn't been populated
l_Appointments = Appointment[Zoho_Inventory_Package_Slips == null] sort by Added_Time desc range from 0 to 100;
for each  c_Appt in l_Appointments
{
	//
	// get package references specified in a previous multi-line text field
	l_PackageRefs = c_Appt.Associated_Package_Slips1.toList();
	//
	// important to declare this as a list of integers
	l_PackagesToAdd = List:Int();
	for each  v_PackageRef in l_PackageRefs
	{
		//
		// fetch the package record
		c_Package = Zoho_Inventory_Package_Slips[ZI_Package_Ref == v_PackageRef];
		if(c_Package.count() > 0)
		{
			l_PackagesToAdd.add(c_Package.ID);
		}
	}
	c_Appt.Zoho_Inventory_Package_Slips=l_PackagesToAdd;
}
  1.  // 
  2.  // get 100 most recent appointments where this field hasn't been populated 
  3.  l_Appointments = Appointment[Zoho_Inventory_Package_Slips == null] sort by Added_Time desc range from 0 to 100
  4.  for each  c_Appt in l_Appointments 
  5.  { 
  6.      // 
  7.      // get package references specified in a previous multi-line text field 
  8.      l_PackageRefs = c_Appt.Associated_Package_Slips1.toList()
  9.      // 
  10.      // important to declare this as a list of integers 
  11.      l_PackagesToAdd = List:Int()
  12.      for each  v_PackageRef in l_PackageRefs 
  13.      { 
  14.          // 
  15.          // fetch the package record 
  16.          c_Package = Zoho_Inventory_Package_Slips[ZI_Package_Ref == v_PackageRef]
  17.          if(c_Package.count() > 0) 
  18.          { 
  19.              l_PackagesToAdd.add(c_Package.ID)
  20.          } 
  21.      } 
  22.      c_Appt.Zoho_Inventory_Package_Slips=l_PackagesToAdd; 
  23.  } 

Error(s:
Previously my code below was used and it wouldn't work. The difference to the above is that I was trying to add to the multi-lookup directly:
copyraw
//
	for each  v_PackageRef in l_PackageRefs
	{
		//
		// fetch the package record
		c_Package = Zoho_Inventory_Package_Slips[ZI_Package_Ref == v_PackageRef];
		if(c_Package.count() > 0)
		{
			c_Appt.Zoho_Inventory_Package_Slips.add(c_Package.ID);
		}
	}
// doesn't work
  1.  // 
  2.      for each  v_PackageRef in l_PackageRefs 
  3.      { 
  4.          // 
  5.          // fetch the package record 
  6.          c_Package = Zoho_Inventory_Package_Slips[ZI_Package_Ref == v_PackageRef]
  7.          if(c_Package.count() > 0) 
  8.          { 
  9.              c_Appt.Zoho_Inventory_Package_Slips.add(c_Package.ID)
  10.          } 
  11.      } 
  12.  // doesn't work
