How does the user validation works for properties in PRPC :

A property value that is supplied by user may be valid or invalid. Pages containing one or more invalid values can not be saved to the database. When process commander detects an invalid value, it adds a message to the page to mark this discovery.
Two important points here are,
        1. The invalid values remain on the clipboard
        2. The user is not automatically notified of the invalid value

Five kinds of rules basically support the user validation:
1. Property Rules ( Rule-Obj-Property ) : It can serve the purpose of validation in 3 ways
a. Table edits constrain the allowable values.
b. Type of property will restrict the format
c. Max allowable length
2. Edit Input values ( Rule-Edit-Input ) : These can convert the user entered input values into an internal format
3. Edit Validate Rules ( Rule-Edit-Validate ) : these are custom java routine functions which can further test the format of the input
4. Field Values ( Rule-Obj-FiledValue ) : These provide configurable list of acceptable values
5. Multii property Validation rules (Rule-Obj-Validate): These rules are used to apply multiple edit validate rules to act at once. If a value fails any of these validations, the system notes this in a message associated with the property or with the clipboard page containing the property

What are the different parsing mechanisms are available in PRPC?

XML Parsing (Apply-Parse-XML method)
Java Parsing

Concentrate on required fields of every rule (Rule that you are familiar with )

For Rule-Obj-Class Rules, history is mandatory.

How to open the work object s

Obj-Open   Open an instance stored in the PegaRULES database or in certain cases an external database.
Obj-Open-by-Handle    Open an instance using a permanent unique key.
Obj-Refresh-and-Lock  Open an instance and acquire a lock.

Tell me how to acquire locking in PRPC?

Process Commander has several locking mechanisms:
=> You can lock a RuleSet version with passwords, preventing any changes to the rules associated with that RuleSet or version.
=> A requestor may acquire temporary exclusive access to an instance, preventing other requestors from updating or deleting it.
=> You can lock an application rule (Rule-Application rule type) with a password, preventing others from changing that rule instance until they enter the password.

Obj-Refresh-and-Lock   Open an instance and acquire a lock.
Page-Unlock            Release a lock held after Commit.

=> Info — Record as INFO severity
=> Warn — Record as WARN severity
=> Error — Record as ERROR severity; most severe. s
=> InfoForced — always record as INFO event.

Tell me about the pz, px,py properties ?

1. PRPC standard properties are prefixed either with px or py or pz
i. Px – Computed properties that users can see on a form, but can’t directly enter or change ( Such as pxCreateDateTime). To alter this values activities can use a step method called Property-Set-Special metod
ii. Py – Properties that users can enter or change via direct input ( such as pyDescription ) . To assign these values programmatically, activities can use step method called Property-Set method
iii. Pz – Properties that are reserved for internal use ( such as pzInsKey). User can’t see, enter or change these properties
