Child case queries performance can be slow
Valid from Pega Version 7.2
Some customers have reported that performance is slow when they execute queries on child cases. This issue is often indicated by PEGA0005 (query time exceeded limit) alerts that can be correlated to these queries in the logs. To resolve the issue, add a database index to each of your work tables by using a multicolumn index on the pxCoverInsKey, pxObjClass, and pyStatusWork columns.
See Performance improvements for child case queries.
Verify ML Readiness error: Upgrades from Pega 7.1.0 through 7.1.8 do not replace nonversioned rules
Valid from Pega Version 7.2
Upgrading from any Pega 7 Platform version between Pega 7.1 and Pega 7.1.8 to Pega 7.2 does not automatically replace nonversioned rules. If you revalidated and saved a Pega 7.1.x rule after the timestamp on the Pega 7.2 version of the rule, upgrading to Pega 7.2 does not overwrite the saved rule. You might see either of the following behaviors:
- The upgrade fails with the following error message:
Verify ML Readiness - The upgrade succeeds, but you might be unable to open changed rule forms.
If the upgrade fails, see the Pega 7 Platform Upgrade Guide to force the upgrade.
This known issue does not affect Pega 7.1.9. After the upgrade has finished, apply Hotfix 27288. For information about obtaining and applying hotfixes, see Hotfix Manager.
Extension attributes are not supported in PMML models
Valid from Pega Version 7.3.1
Models in the Predictive Model Markup Language (PMML) format version 4.3 that contain extension attributes with the x- prefix are not valid. These extension attributes are deprecated; you must use extension elements instead. In addition, if the output type of any output field in the model is set to FLOAT, change it to DOUBLE.
For more information, see PMML 4.3 - General Structure in the Data Mining Group documentation.
The Upload responses action is not supported for adaptive models with customized context
Valid from Pega Version 7.3.1
A default instance of the Adaptive Model rule contains five model identifiers (.pyIssue, .pyGroup, .pyName, .pyDirection, .pyChannel) that are used to partition adaptive models. If you add other identifiers in your Adaptive Model rule instance, you cannot upload responses to this instance with the Upload Responses wizard and the following error is displayed: The Flow Action post-processing activity pzUploadCSVFile failed: Cannot parse csv file.You can still train such adaptive models with data flows.
For more information, see Training adaptive models in bulk with data flows, Model context, and Uploading customer responses.
Use fast processing option does not work
Valid from Pega Version 7.3.1
The Use fast processing option on Connect REST and Service REST rule forms does not work unless you obtain the HFix-43000 hotfix from Global Customer Service.
Use the following data model guidelines when using fast processing:
- The JSON property names and the clipboard property names must match.
- The JSON tree structure and the clipboard tree structure must be similar.
- The scalar arrays in JSON must be mapped to the clipboard as page lists.
- Multi-dimensional arrays must be mapped into page lists of page lists with the same embedded property names.
In addition, page groups, value groups, and Java objects are not supported by fast processing.
Upgrading Adaptive Decision Manager data mart tables might fail
Valid from Pega Version 7.3.1
Issue: Upgrade from 7.3 to 7.3.1 fails if the data contained in the pxInsName column of the PR_DATA_DM_ADMMART_PRED_FACT table is longer than 128 characters.
Reason: During the Pega Platform™ upgrade from 7.3 to 7.3.1, data in the Adaptive Decision Manager (ADM) data mart tables is migrated from the PR_DATA_DM_ADMMART_PRED_FACT table to the PR_DATA_DM_ADMMART_MDL_FACT table. In Pega 7.3.1, ADM uses only the PR_DATA_DM_ADMMART_MDL_FACT table where the pxInsName property can store values that are 128 characters long. In Pega Platform 7.3, the pxInsName property in the PR_DATA_DM_ADMMART_PRED_FACT table can store values that are 255 characters long. If the pxInsName property contains values that are longer that 128 characters, the upgrade fails.
Resolution: Issue an ALTER TABLE statement to change the pxInsName column size to 255 characters and resume the upgrade. For example:
ALTER TABLE rules.pr_data_dm_admmart_pred ALTER COLUMN pxInsName TYPE varchar(255);
