Updating a parameter in a batch of processes - sample code?

[tom....@mycit.ie]

I have > 100 processes that were initialised with an incorrect parameter value. To avoid manually opening each of them and adding a Computed parameter with the correct value, I'm hoping it's possible to create a process to do this using the RunMyProcess API. Is there any sample code available that implements the equivalent of:

for each process P returned by process report A do
set P.Computed.param = Y
end do

Hi Tom,

There's no code to perform that, you'll need to design a process to do the job.

I'll design a draft version of the process you would need on my side and share with you some screenshots of it to help you design yours.

I'll try to find a slot tomorrow to do that.

Hi Tom,

Sorry for late reply, here's the process you need :

First box will list and store in an array all the IDs of the instances you want to update.

Second box will loop on this array and call a subprocess to update each instance.

1) Start event

a. Output variables

Please find below the output variables (and their values) you should create on the start event of the process.

• current : 0
  
• end : false
  
• list_instance_ids : []
  

2) List processes instances box

This box is a loop on a Connector.

The connector you need is the "Get anything (xml output V1)", that you can find in the connector library, under the "RunMyProcess - Secured Connection" provider.

The loop has to be configured as a While loop, with end="false" as its condition.

a. Input variables

The only input variable is rmp_url, and it should contain the URL of your process report containing all the instances you want to update.

To retrieve the URL of your report, open your process report within the portal, and click on the RSS feed icon :

Then copy the URL of the page that has just opened, without the https://live.runmyprocess.com/

Finally, in the URL, replace (1) nb=20 by nb=100 and (2) first=0 by first=${current}

Here you have your rmp_url value.

b. Output variables

You've got 3 output variables here :

• current : ${current?number+100}
  
• list_instance_ids :

<#assign tmp=list_instance_ids>

<#if P_result.feed.entry?exists>

<#if P_result.feed.entry?is_sequence>

<#list P_result.feed.entry as x>

<#assign tmp=tmp+["${x.id}"]>

</#list>

<#else>

<#assign tmp=tmp+["${P_result.feed.entry.id}"]>

</#if>

</#if>

${tmp}

• end :
  

<#if P_result.feed.entry?exists>false<#else>true</#if>

3) Update instances box

This box is a loop on a Subprocess.

The subprocess you will have to create and plug here is the one shown below. We'll come back to it later on.

The loop has to be configured as a Multi-instance sequential loop, with ${list_instance_ids} as its array.

a. Input variables

• current_instance : ${list_instance_ids[P_index]}

b. Subprocess

3.1) Get instance details connector box

This box is a Connector.

The connector you need is the "Get details of a process instance", that you can find in the connector library, under the "RunMyProcess - Secured Connection" provider.

a. Input variables

• P_customer : ${P_customer}
  
• request_id : ${current_instance}
  

b. Output variables

• computed : ${P_result.feed.entry[1].content.P_value}
  
• execution_path : ${P_result.feed.entry[3].content.P_value}

3.2) Update instance connector box

The connector you need is the "Modify process request instance", that you can find in the connector library, under the "RunMyProcess - Secured Connection" provider.

a. Input variables

• comment : You can put the comment you want (it's just like the comment you type in when you restart a process)
  
• P_customer : ${P_customer}
• computed : ${computed}
• computed.the_name_of_the_variable_you_want_to_update : the updated value of your variable
• computed : ${encrypt('BASE64',computed)}
• execution_path : ${execution_path}
• request_id : ${request_id}
• state : 102

That's all !

Hope that's clear enough

Thanks Gareth, it's a very comprehensive response!
I've implemented this to test stage and have two issues:

1) the RSS feed URL of the process report causes a failure - it contains some pipe characters (|) which Jave doesn't like. When I replaced each of these by %7C the problem was resolved.

2) after running the update process on a number of real processes, I checked the Revisions screen for each. The comment text in the most recent revision is garbled binary - it's not the text I supplied to the Update Process Instance RMP API call. I'm concerned that if the comment text is corrupt/wrongly encoded that other attributes of the process state may be similarly affected by the update. Is there a simple explanation for the unreadable comment text or is there any way to verify the integrity of process state after update?

[Gareth Thiveux]

Hi Tom,

My mistake, as specified in the description of the "Modify process request instance" connector, the comment variable also has to be base64 encoded :

Parameters :

comment : comment to be added to relaunch method in base64 (function encrypt)

computed : all computed parameter in base64 (function encrypt) - ${P_result.feed.entry[1].content.P_value} on Get process request instance

execution_path : not encoded - ${P_result.feed.entry[3].content.P_value} on Get process request instance

state : 102 (keep as current) - 103 (waiting for resume)

That's all worked perfectly. Many thanks
