In SAS Customer Intelligence Studio, you might receive an error message when you use static Link nodes in campaigns. This problem happens when you perform steps similar to the following:

1. Create a campaign called Layer1 that contains a Select node and a Cell node.
2. Make the Cell node available for linking and clear the property Use the most current data when referenced by a link. Choose whether to execute the campaign and then save and close the campaign.
3. Create a campaign called Layer2 that contains a Link node that points to the Cell node in Layer1 and that contains a Cell node.
4. Make the Cell node available for linking and clear the property Use the most current data when referenced by a link. Choose whether to execute the campaign. Then save and close the campaign.
5. Create a campaign called Layer3 with a Link node that is linked to the Cell node in Layer2. Then add one of the following types of nodes:  LIMIT, PRIO, AND,  OR, or PROCESS.
6. Execute campaign Layer3. When you execute the campaign, the counts are updated properly.
7. Change the selection criteria in campaign Layer1. Then execute and save the campaign.
8. Execute the Layer3 campaign again.

When you execute Layer3 again, the execution fails and the following error is generated:

As a workaround, close all three Layer campaigns and make sure that the Cell nodes do have counts before you save the campaigns.

Click the Hot Fix tab in this note to access the hot fix for this issue.

Note: After you apply the hot fix, the following new Java argument is introduced:

When this property is enabled, link nodes *always* hold a copy of the MATable to which they point.

• For Microsoft Windows operating environments (in which the servers are started as Windows services):

Navigate to the SAS-configuration-directory\Lev1\Web\WebAppServer\SASServer6_1\conf directory and add the new argument to the wrapper.conf file, as shown below:

In this argument, XX represents the next number in the sequence that already exists in the file. Modify XX to be the next number in that sequence.

• For Linux or other UNIX operating environments:

Add the option to the setenv.sh file, as shown below:

The setenv.sh file is typically located in the SAS-configuration-directory/Lev1/Web/WebAppServer/SASServer6_1/bin directory.

After you add the argument, restart the middle tier so that the setting can take effect.

Note: It is assumed that the following properties are also set:

These options are described in the following SAS Notes:

• SAS Note 60225, "Enabling the option "Use the most current data when referenced by a link" only returns current data when a campaign is executed"
• SAS Note 61240, Counts are not updated when you execute a campaign multiple times in the same SAS^® Customer Intelligence Studio session
