Explain the Skimming concept in PEGA for PEGA CSSA?

Skimming produces a variant of the Rule Set that includes the highest version of the current rules. The wizard will recognize the highest-numbered version for each rule instance in the given Rule Set and generate a copy with an even higher number that you choose. Let us discuss the skimming concept within Pega.

Skimming Up (Major version) in PEGA

The wizard uses the number you assign as the main portion of the target version for a major skim, and sets the minor and patch values of the target version to ‘01.’

Pick Software > Rule Administration > Skim a Rule Set…

Select a Rule Set and major version as the source in the form that appears with the Major Version Rule Set Skim radio button selected, and specify a two-digit number for the current major version.

Increase the latest main version number by 1. Usually, Up to 99. You can select any higher number. Jumping to a high number can limit your ability to carry out future growth.

Skimming Up (Minor version) in PEGA

The wizard carries forward the main version of the Rule Set source version for a small skim and uses the numbers you assign as the minor and patch sections of the goal version.

Pick Software > Rule Administration > Skim a Rule Set…

Select a Rule Set as the source in the form that appears, with the Minor Version Rule Set Skim button selected, and from the two picklists displaying all patch versions in that minor version, select the lowest and highest versions that will be verified by the wizard. Then include a target version in the To New Version sector.

Following skimming in PEGA

Lock each of the source Rule Set versions on its Protection tab when your skim operation is complete. This means that only in the newly-created version can developers add or change rules.

Down Compress in PEGA

Compressing several versions of a RuleSet into one version and discarding the source versions is often useful. For example, you may want to consolidate them if a series of development attempts have left a confusingly large number of versions of Rule Set.

Pick Tools > Rule Management > Rule Set Copy/Move.

The Maintenance wizard for Rule Set appears in PEGA

Pick the Transfer radio button, and then move the versions of the Rule Set that you want to compress to the right-side box. Do not include in this list the goal version.

Choosing a Rule Sets source in PEGA

Source Order is meaningful. When the compression happens, the wizard checks the Rule Sets in the right-hand list, starting at the top, and gathers the first version of each rule it finds, except as mentioned below. There are discarded redundant rules. The wizard deletes the Rule Sets source when processing is complete.

Compress Rule Sets with prerequisites starting from the first dependency rule set. For instance, if Rule Set A has Rule Set B as a prerequisite, and Rule Set B has Rule Set C as a prerequisite, then A, B, and C are the order in which you should compress Rule Sets. You risk missing any rules if you compact Rule Sets in the order C, B, and A.

Overwriting in PEGA

Only click Next. A screen for feedback appears. Click Next if you are pleased with your settings and choices.

A report indicates the number of rules compressed into the target version of the Rule Set when the process is completed, and the source versions are removed.

Combining Merge versions for Rule Set in PEGA

You can combine several Rule Set versions into a new Rule Set. This can be useful when enhancing the application’s organization and encouraging the reuse of rules.

Pick Tools > Rule Management > Rule Set Copy/Move. The Maintenance wizard for Rule Set appears.

Wizard Care Set of Laws in PEGA

Select the radio button for Copy or Transfer.

If you choose Copy, the Rule Sets source you chose will be unaffected.

If you select Transfer, after copying the highest version of each rule from the Rule Sets source to the Rule Set goal, the Rule Sets source will be deleted.

From the list on the left, pick one or more rule sets and pass them to the list on the right. The Rule Sets that will be processed are these. When processing starts, the wizard tests the Rule Sets in the right-hand list, beginning at the top of the list, and collects the first version of each rule that it finds. In the Rule Set Versions list, duplicate rules are ignored, not copied to the target.

Provide the name of the destination Rule Set and the version to receive the copied rules to the right of the form. Specify how to manage disputes with the wizard — if a source rule overwrites a copy of a rule that already exists in the Rule Set goal.
