send value from business rule to client script

[FIKRI BENBRAHIM]

He lo every one,

I want to send a sys_id of a reference field from a Business rule to a Client Script. For that i use the global variable SCRATCHPAD in business rule to fill in the value from the database into scratchpads property, then i user the same scratchpad value in a client script to read the value from the scratchpad. 

But i can't manage to fill in the value  of the reference field named "assignment_group" in the Business rule because the logs show an empty reference fields value. Here is my Business rules onDisplay code:

  g_scratchpad.Assignement_Groupe_SysId = current.assignment_group;
  gs.log('g_scratchpad.Assignement_Groupe_SysId = '+g_scratchpad.Assignement_Groupe_SysId+'!!!!!!!!!!!!');

Can someone help me solve this problem please? Because i am a beginner in servicenow

When i check the log, i find an empty value in g_scratchpad.Assignement_Groupe.getDisplayValue().

Thanks for your reply Shashikant Yadav. But i have already seen this  question in the community and it's not helping. 

I guess getDisplayValue() whould have healped if i had the sys_id

Yes, because assignment group is reference field.

What value you are getting in current.assignment_group? Can you pass the static value under scratchpad and check the log

g_scratchpad.Assignement_Groupe = 'Test Value';

Hello all,

Actually the business rule has to be on Display in order for the scratchpad variable to work.

See this link related to scratchpad global variables with business rule: Link.

See the link related to using the scratchpad variables of a workflow: Link. 

Kind regards
