Field with fixed value in more than one record

OL Connect Professional DataMapper
1

Hello,

i have a little problem with the datamapper.
I need to save a value from previous record.

Or could we use a public value in the datamapper, and how?

In the example, in the second record, there are 14, 13, 10, 12 missing, which has to be remembered from the previous.

How can I achive this?

Here a little example about the problem:

you may store the value in a javascript variable.

The question for me is, where I can do this in the datamapper.

if it’s useful to use a variable to hold a value of a previous record depends on what you are trying to do.
What do you need to achieve at the end?
Maybe your data are transactional data, which would need loops to get all the detail fields imported?
So maybe you just would need to redefine your record structure?

Hi, the performance generating the Records is also an issue. Many Loops = low performance? @MartinS Greetz

Due tu multi-threading in the Datamapping process, storing values in global variables wouldn’t work. Let’s say you have 1000 records. Multi-threading kicks in and the record 1-100 is given to thread 1, 101-200 to thread 2, etc… So between record 100 and 101, no comparison is possible has they are handle by two separated thread.

What could work would be to achieve this in the metadata of Workflow using a script.
So in Workflow, after your Execute Datamapping step, which has its Output Type set to Metadata, you would have a script that go through all the metadata. It would look at the metadata’s fields holding the value from your data (14, 13, 12, 10). If they aren’t empty, it stores them into local variables in the script. If they are empty, it populates the metadata’s fields with it.

Then in your Content Creation step, you make sure you have check the Update Records from Metadata check box. That would fill-up the missing value just before the creation of the content (PDF).

Here’s a script that takes the first name from the first record and apply it to all other record. You can then modify it for your purpose:

// Load the Datamapper's resulting metadata file
var metadata = new ActiveXObject("MetadataLib.MetaFile");
metadata.LoadFromFile(Watch.GetMetadataFileName());

var nbRecord = metadata.Job().Group(0).Count;
var firstName = metadata.Job().Group(0).Document(0).FieldByName('_vger_fld_FirstName');

//Loop through all document and set the first name to the one of the first record 
for(var index = 0; index < nbRecord ; index++)
{
   metadata.Job().Group(0).Document(index).Fields.Add('_vger_fld_FirstName',firstName);

}

metadata.SaveTofile(Watch.GetMetadataFileName());
